For now, we don't NATIVE_SYSTEM_HEADER_DIR because it breaks the
build. However, it points to Glibc in the Nix store (not /usr/include)
so it's kind of okay.
Even if using profiledbootstrap. This was unsafe before 4.8, and
then the documentation was not fixed on time.
The documentation got fixed here:
c763997f34
But the actual code was already fixed here:
5d2fca09d5
So this is safe both for GCC 4.8 and GCC 4.9.
(Or at least restore it to the same level as brokenness as before the
staging merge. I.e. it depends on gcc-apple, which doesn't build on
standard 10.9 systems.)
Having a separate lib64 is bad because it requires special-casing in
lots of places.
Previously done in e4a11b4d92, which
apparently got lost going from 4.6 to 4.8.
Recent versions of Xcode don't install headers in /usr/include but
in a directory like
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include
So use that instead, falling back to /usr/include in case of an older
version of Xcode.
Somewhere the no-sys-dirs.patch got disabled, so gcc was looking in
/usr/local/include and /usr/lib. Since I can't fix the patch easily,
I've borrowed the --sysroot trick from clang-wrapper. This causes
builtin paths to be prefixed with /var/empty
(e.g. /var/empty/usr/lib), which don't exist.
This includes a lot of fixes for cross-building to Windows and Mac OS X
and could possibly fix things even for non-cross-builds, like for
example OpenSSL on Windows.
The main reason for merging this in 14.04 already is that we already
have runInWindowsVM in master and it doesn't work until we actually
cross-build Cygwin's setup binary as the upstream version is a fast
moving target which gets _overwritten_ on every new release.

On MinGW, we're passing these programs to the configure script, but this
obviously won't work for non-autoconf-based projects.

Both branches have quite a lot in common, so it's time for a merge and
do the cleanups with respect to both implementations and also generalize
both implementations as much as possible.
This also closes#1876.
