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).
