Unify glibc for bash and python and ghc


I noticed that glibc version used by bash and python and ghc might get out of sync. I preload python as a shared library and it breaks shell commands.

I think I need to customize bash derivation to use it with newer glibc version.

I didn’t touch glibc anywhere in my default.nix

nixpkgs only uses one glibc at a time. If you’ve got different packages using different glibc’s, it’s probably because you’ve gotten them from different revisions of nixpkgs.
