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.
path worth a "-rpath" entry.
This put a problem in the bootstrap, where we built 'zlib' and wanted to link programs with it, and while they got linked well, at runtime the boostrap-tools zlib came first on rpath becaue
the ld call was done with "-dynamic-linker ..." before "-lz".
I saw this trouble on the fuloong, where the zlib in boostrap-tools is not
runtime compatible with that binutils are linked to.

it properly put the rpath for directly passed .so files, and additionally it
works much faster than the old ld-wrapper.

because it makes linking very slow. Use bash's =~ operator instead
(and only once for each argument). We depend on bash already anyway
because of arrays so it's not a problem.

regexp looking for such ld arguments did not work well with "--soname=xxx.so".
Now I added the condition that the argument should not start with a hyphen, for
it to be possibly considered a .so file to link with.

Removing any reference to the gcc-wrapper2, as now the gcc-wrapper already conveys
the changes, I created gcc-wrapper2 in trunk for.

* Put the Glibc linker flags in front of the GCC linker flags. Needed
for the stdenv-linux bootstrap.

Glibc. This is useful when building GCC.
* gcc-wrapper: the dynamic linker has a different name on x86_64 and
powerpc.
* gcc-wrapper: "glibc" -> "libc", because someday we might support
different C libraries.
* gcc: don't do a multilib build (e.g., 32-bit support on x86_64),
don't need it.
* gcc: merge in support for static builds.
* gcc: various simplifications in the compiler/linker flags, hope they
work.

libgcc of the gcc being built, not the gcc building it.
* Only include a directory in the rpath of an executable/library if it
is actually used. Before, the `/lib' directory of every build input
was added to the rpath, causing many unnecessary retained
dependencies. For instance, Perl has a `/lib' directory, but most
applications whose build process uses Perl don't actually link
against Perl. (Also added a test for this.)
* After building glibc, remove glibcbug, to prevent a retained
dependency on gcc.
* Add a newline after `building X' in GNU Make.

On the downside, the build process of stdenvLinux builds gcc 9 times
(3 x 3 bootstrap stages). That's a bit excessive.

checked whether absolute paths passed to gcc/ld refer to the store,
which is wrong: they can also refer to the build tree
(/tmp/nix-...).
* Less static composition in the construction of stdenv-nix-linux:
gcc-wrapper and generic are now passed in as arguments, rather then
referenced by relative path. This makes it easier to hack on a
specific stage of the bootstrap process (before, a change to, e.g.,
generic/setup.sh would cause all bootstrap stages to be redone).

- gcc/ld-wrappers have been factored out into a separate
derivation. This allows a working gcc to be installed in the user
environment. (Previously the Nix gcc didn't work because it
needed a whole bunch of flags to point to glibc.)
- Better modularity: packages can specify hooks into the setup
scripts. For instance, setup no longer knows about the
PKG_CONFIG_PATH variable; pkgconfig can set it up instead.
- gcc not longer depends on binutils. This simplifies the bootstrap
process.
