To test this I built a version of the compiler with `dontStrip = True`
and the vanilla version. The size of the result is both 1.4gb which
indicates that the stripping doesn't do anything meaningful.
Not stripping means that the debug rts is properly packages as it
contains DWARF information and unused debugging symbols.

`pkgsBuildTarget` allows us to avoid repeated and confusing conditions.
The others merely provide clarity for one the foreign package set's
target platform matters.
Use the system `libffi` (`ie` nixpkgs's) instead of built-in libffi
from ghc source tree.
This will prevent library conflict when ghc dynamically links haskell
packages (linked with ghc built-in libffi) and any external library
which uses nixpkgs `libffi`.
Closes https://github.com/NixOS/nixpkgs/pull/55208.
If the nix store lives on NFS, `ghc 8.2.1` is unable to build a package
database. This bug was fixed by @bgamari in `ghc 8.2.2` here:
https://ghc.haskell.org/trac/ghc/ticket/13945
This commit upgrades the unpacked bootstrap GHC version, so that we can build
newer versions of GHC even if the store is on NFS.
We keep the latest minor release of each one of the last 3 major releases,
which currently are GHC versions 8.2.2, 8.4.4, and 8.6.1. We also have
ghc-HEAD, but this doesn't count.
Dropping these compilers implied that we have to drop the corresponding
versions of ghcjs, too. We can also drop a shitload of obsolete compiler
patches that newer versions no longer need.
At some point, we can probably simplify the generic builder, too.
The compilers themselves can pull them from `bootPkgs`, where they
should always come from anyways. This enforces that, simplifies that
code, and allows use to avoid more `rec { ... }` too.
These prebuilt binaries need to be used with glibc,
it doesn't matter what we're using otherwise.
This may seem a bit strange but has the huge advantage
of not needing to create/host/download musl-specific variants,
and instead continue to use the official ones from upstream.
Fixes build with "muslpi" (armv6l-unknown-linux-musleabihf).
This was done via patch at first but it wouldn't apply to both at once,
and it's probably best to stick to just having musl clones for now
(instead of patching 8.6.1 targets into 8.4.3 and hoping that's okay).
enableShared in generic-builder.nix should default to what the GHC
compiler was compiled with. Add a passthru to all of the GHC compilers
to hold the value of enableShared. If enableShared is not set in the
GHC we just use false as the default value for enableSharedLibraries.
Note: I may have missed some compilers. Only GHC & GHCJS are covered
by this commit but this shouldn’t break evaluation of anything else.
* grab patches from gentoo to fix various 2-stage cross build system
bugs
* explicitly set CrossCompilePrefix to the expected targetPrefix
-- ensures everything has expected name and location
-- fixes lack of prefix'ing when doing glibc -> musl "cross"
* Stage1Only: only set if doing "true" cross
* don't try to specify include/lib dirs for ncurses on cross
-- only used by terminfo which actually removed the include option,
and the lib option doesn't seem to do anything other than
confuse the situation re:cross.
Fixes#37522
nixpkgs#37012 and nixpkgs#37707 introduces the setup-hooks for libiconv, which inject `-liconv` into the `NIX_LDFLAGS`. This breaks horribly on windows where the linker end up having no idea how to linke `-liconv`. The configure.ac file specifically ignores libiconv on windows.

Something goes amiss in the configurePhase and binaries start picking up
system binaries and everything falls apart. Patch the configure script
to use a bourne shell out of the store, and things are happier.

The hack of using `crossConfig` to enforce stricter handling of
dependencies is replaced with a dedicated `strictDeps` for that purpose.
(Experience has shown that my punning was a terrible idea that made more
difficult and embarrising to teach teach.)
Now that is is clear, a few packages now use `strictDeps`, to fix
various bugs:
- bintools-wrapper and cc-wrapper
Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.
The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:
```
ISA: ARMv8 {-A, -R, -M}
/ \
Mode: Aarch32 Aarch64
| / \
Encoding: A64 A32 T32
```
At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.
The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

For some reason compiling the proper GHC from the binary one eventually
segfaults at some point.
Since it has never worked, just disable it and investigate later.
None of these old compilers are used anywhere in Nixpkgs, and keeping those
builds working in the face of regular updates of GCC, binutils, and whatnot is
too much effort for no obvious benefit.
