Description of changes

This commit deduplicates libgcc-related boilerplate which appears in every version of our gcc expression, by moving it into libgcc.nix.

I will be submitting a separate PR which changes this boilerplate, but that PR will be much easier to review if I can make the change in just one place.

Meanwhile, this commit has no effect on eval:
