Eelco Dolstra 0fd59fd7a4 * Re-enabled purity checking: it should work now. First we only
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).

# The Nix `gcc' derivation is not directly usable, since it doesn't
# know where the C library and standard header files are. Therefore
# the compiler produced by that package cannot be installed directly
# in a user environment and used from the command line. This
# derivation provides a wrapper that sets up the right environment
# variables so that the compiler and the linker just "work".
