Hi Guix!

I figured out this morning that my guix pull profile ("current") was more than 1GB. Looking at the closure, I found a few oddities.

There's gcc in there, which is the second most important contributor after guix-*-modules (150 MB). It's referenced by gcc-toolchain, itself only referenced by the guile-wrapper we build in (guix self). Can we get rid of it?

There are three versions of guile (50 MB each). Can we settle for only one?

Then maybe less important because they're small:

There are two libffi, gzip, zlib, libgc, bash-minimal, xz, pkg-config and libunistring.

We have bash-minimal and bash-static. The latter is a bit bigger than the former. Maybe we can keep only bash-minimal?
