08f3a60e7b cc-wrapper: Remove dead code
ccPath is only defined below, so this condition would never be true.

Worse, that's not quite true: what if somebody happend to have `/clang`
and no sandboxing. Boy, wouldn't that be annoying to debug!

cc-wrapper: fix LD_DYLD_PATH on darwin
Having multiple compilers in the build environment would result in an
invalid LD_DYLD_PATH like /usr/lib/dyld/usr/lib/dyld.
Since the path is hardcoded in XNU it can't be anything but
/usr/lib/dyld anyway.

07674788d6 Respect NIX_DONT_SET_RPATH when .so appears in the command line
Unified processing of command line arguments in ld-wrapper broke support for
`NIX_DONT_SET_RPATH` and revealed that ld-wrapper adds the directory of its
`-plugin` argument to runpath. This pull request fixes that. It treats
`dir/libname.so` as `-L dir -l name`, because this is how `ld.so` interprets
resulting binary: with `dir` in `RUNPATH` and the bare `libname.so` (without
`dir`) in `NEEDED`, it looks for `libname.so` in each `RUNPATH` and chooses the
first, even when the linker was invoked with an absolute path to `.so`.

1cd74ac70a cc-wrapper: Make sure symbol tables of child delegators is not empty
As described in https://github.com/NixOS/nixpkgs/issues/18461, MacOS no
longer accepts dylibs which only reexport other dylibs, because their
symbol tables are empty. To get around this, we define an object file
with a single "private extern" symbol, which hopefully won't clobber
anything.

4964b104b9 ld-wrapper: Optimize expanding rpath
The time to expand rpath was proportional to the number of -L flags times the
number of -l flags.  Now it is proportional to their sum (assuming constant
number of files in each directory in an -L flag).

b087618ac0 Revert "stdenv: Store one package per line in nix-support/propagated-*"
As @oxij points out in [1], this breakage is especially serious because
it changes the contents of built environments without a corresonding
change in their hashes. Also, the revert is easier than I thought.

This reverts commit 3cb745d5a6.

3cb745d5a6 stdenv: Store one package per line in nix-support/propagated-*
This makes those files a bit easier to read. Also, for what it's worth,
it brings us one baby step closer to handling spaces in store paths.

Also, I optimized handling of many transitive deps with read. Probably,
not very beneficial, but nice to enforce the pkg-per-line structure.
Doing so let me find much dubious code and fix it.

Two misc notes:

 - `propagated-user-env-packages` also needed to be adjusted as
   sometimes it is copied to/from the propagated input files.

 - `local fd` should ensure that file descriptors aren't clobbered
   during recursion.

c1fb71b74a cc-wrapper: when cross building, wedge in setting AR, AS, and LD env vars to their cross building versions
I think it's ok to export things which aren't wrapped. The cc-wrapper
can be thought of as responsible for all of binutils and the c
compiler, only wrapping those binaries which are necessary to
interposition---as opposed to all binaries it thinks are relevaant.

Conversely, adding the setup hook to the unwrapped compilers would be
unforunate as hooks are ugly hacks and the compilers themselves take
a long time to rebuild. Better to wholely separate "pure packages" from
hacks.

8a7433fca4 cc-wrapper: Temporarily got to great lengths to avoid mass-rebuild

making native the "identity cross").

0f0383394d cc-wrapper: Salt environment variables with LLVM triples
We now (on cross) require per-target flag interposition by putting the
triple in the names of the relevant environment variables, e.g:

export NIX_arm_unknown_linux_gnu_CFLAGS_COMPILE=...

The wrapper also has a `infixSalt` attribute (and "_" prefixed and
suffixed variants) to assist downstream packages.

Note how that the dashes are replaced to keep the identifier valid.
Using names like this allows us to keep the settings for different
compilers seperate.

I think it might be even better to use names like `NIX_{BUILD,HOST}...`
using the platform's role rather than the platform itself, but this
would be more work as the previous stages' tools would have to be re-
wrapped to take on their new role. I therefore didn't do this for now,
but that route should be thoroughly explored in the future.

cc-wrapper: add stackcheck hardening (stack clash)
This fixes the Stack Clash issue rediscovered by Qualys. See
https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt
for more information on the topic, specifically section III.

We don't have the kernel mitigation available because it is a Grsecurity
feature which we don't support anymore. Other distributions like Gentoo
Hardened and Arch already have `-fstack-check` enabled by default.

See the Gentoo page on Stack Clash for more information on this solution:
https://wiki.gentoo.org/wiki/Hardened/Gentoo_Hardened_and_Stack_Clash

This unfortunately doesn't apply to clang because `-fstack-check` is a
noop there. Note that the GCC implementation also has problems that could
be exploited to circumvent these checks but it is still better than
keeping it disabled.

175461e09b cc-wrapper: don't expand $ in response files
This makes the response file handling more consistent with GCC.

For example, a reponse file may contain:

GCC will treat this as a double quoted string and not expand the
variable reference.  Previously, cc-wrapper would expand the variable
in the same was as if the string was provided on the command line.

aff1f4ab94 Use general hardening flag toggle lists
The following parameters are now available:

  * hardeningDisable
    To disable specific hardening flags
  * hardeningEnable
    To enable specific hardening flags

Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.

cc-wrapper supports the following flags:

  * fortify
  * stackprotector
  * pie (disabled by default)
  * pic
  * strictoverflow
  * format
  * relro
  * bindnow

d5bb6a1f9c glibc: Enable separate debug symbols
The importance of glibc makes it worthwhile to provide debug
symbols. However, this revealed an issue with separateDebugInfo: it
was indiscriminately adding --build-id to all ld invocations, while in
fact it should only do that for final links. Glibc also uses non-final
("relocatable") links, leading to subsequent failure to apply a build
ID ("Cannot create .note.gnu.build-id section, --build-id
ignored"). So now ld-wrapper.sh only passes --build-id for final
links.

d96893647d cc-wrapper: fix on darwin
The ld-wrapper.sh script calls `readlink` in some circumstances. We need
to ensure that this is the `readlink` from the `coreutils` package so
that flag support is as expected.

This is accomplished by explicitly setting PATH at the top of each shell
script.

Without doing this, the following happens with a trivial `main.c`:

```
nix-env -f "<nixpkgs>" -iA pkgs.clang
$ clang main.c -L /nix/../nix/store/2ankvagznq062x1gifpxwkk7fp3xwy63-xnu-2422.115.4/Library -o a.out
readlink: illegal option -- f
usage: readlink [-n] [file ...]
```

The key element is the `..` in the path supplied to the linker via a
`-L` flag. With this patch, the above invocation works correctly on
darwin, whose native `/usr/bin/readlink` does not support the `-f` flag.

The explicit path also ensures that the `grep` called by `cc-wrapper.sh`
is the one from Nix.

Fixes #6447

6671bb8be4 Remove gccStdInc
This reverts d927da8dae. Having a copy
of gcc-wrapper/setup-hook.sh is bad for maintainability - it had
already started to diverge. Also, gccStdInc gave a nix-env conflict
with the standard gcc. And it wasn't actually used in Nixpkgs.

Instead, if you really need to change "-isystem" to "-I", you can now
set ccIncludeFlag to "-I".
