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.
something'.
It should not link at least for '-x c-header' and '-x c++-header', and maybe
link for '-x c' or '-x c++', but we expect noone will be linking using these
later strings.
Adding opencv, which required '-x c-header' working, and that's why I have
updated gcc wrapper.

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.

right thing. This is necessary to make libtool detect g++
properly. (Fixes the `libtool: compile: unable to infer tagged
configuration' error on FreeBSD when building Berkeley DB 4.4.)

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.
