- 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.

/usr/lib/crt1.o, while it should be using $glibc/lib/crt1.o. This
quick hack (prepending $glibc/lib to the GCC search path using "-B")
fixes the problem, but a better solution to prevent this sort of
thing is to remove these static paths from gcc.
Note: this problem was found using the pure UML Nix environment
(where we don't have /usr/lib).

against the right dynamic libraries. set-env.sh add the right linker flags to the
NIX_LDFLAGS environment variable, which is passed by gcc-wrapper to the linker.
(In many cases these flags could just be passed through LDFLAGS to configure
scripts; however, in many other cases this doesn't work properly.)

the build and execution environment.
This is very useful. For example, it allows packages built on a SuSE
8.2 system to run on a SuSE 8.1 system (this is because 8.2 has a newer
glibc; packages built against it cannot be dynamically linked against
older glibcs).
Of course, Fix packages should not directly import glibc since that is
very system-specific. Rather, they should import stdenv/stdenv.fix and
in their build scripts source in $stdenv/setup, which will setup the
right environment variables. The idea is that stdenv.fix provides the
basic C/Unix build environment (C compiler, POSIX utilities, etc.).
Note that only the ATerm package currently uses this.
