We usually don’t use the “gcc” package directly in Guix.  Instead we use
“gcc-toolchain”, which also comes with a wrapper around the linker that
ensures that binaries are linked with libraries in the store, ensuring
that things generally just work™.

I think more work would be needed to ensure that packages can actually
successfully be linked with musl, but I’m not at all familiar with this.
I had mixed success with a GCC ARM cross-compiler toolchain linking with
newlib, so I know that it’s not exactly obvious how to do this right,
but I find it hard to understand this.

Have you tried building something that links with the libc provided by
this musl package instead of the GNU libc?  I’m not opposed to adding
the package, but I’d like it to be usable.
