- 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.
