I also had to change this -- I got confusing errors which seemed to have to do with clang including GCC headers.

The problem is that if we do not do that, then I think we default to libstdc++ from LLVM, which never worked for compiling Firefox, as far as I experienced.

This might be a dumb question, but why not? It seems from https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Linux_Prerequisites#Other_distros_and_other_Unix-based_systems that both gcc and clang are supported.

I also changed it here. I'm not sure if both were really necessary.

This is mostly needed for me, where I use this environment variable for only compiling SpiderMonkey using the ./configure $NIX_EXTRA_CONFIGURE_ARGS command line. (more complex in practice, but this is the idea)

This /lib should be removed, because it ends in /lib/lib else.

At least when i try to build within nix-shell ../../nixpkgs-overlays/nixpkgs-mozilla/release.nix -A gecko.x86_64-linux.gcc, that is.

This one /lib is also extraneous. See above.

This change fixes the issue reported in #191 , by making sure that we use the same clang as the one provided in the
stdenvwhen building Gecko, and when usingbindgen.
