`gcc` is already a package installed, but it does not install a `libc` candidate with it. `musl-dev` contains the necessary development files (`crti.o`, `crtn.o`, `Scrt1.o`, `libc.so`, etc.). This was prior requested in rust-lang#68 and is necessary for `proc-macro`s/build scripts to compile, without additional configuration/setup. It also is apparently just a 2% size increase which many consumers are already incurring due to how only effectively bare-metal compilation is possible without it.

I looked into this for a while last night, and I think that this is a good change to make. The improved user experience is well worth the ~2% size increase in my opinion, especially when you consider how many people pull it in themselves.

Can you add this to the Alpine Dockerfiles in both nightly/ and stable/?
You should be able to update all of them at once by running:
./x.py update
