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). svn path=/nixpkgs/trunk/; revision=833
