Package request: glibc
Most Linux binary distributions require glibc to run, including many closed source programs where simply recompiling for musl would be impossible.
There is already an ABUILD written for this which can be found at https://github.com/sgerrand/alpine-pkg-glibc, however it’s only compatible with x86_64. If this were in the official repositories, it would be compatible with every architecture.
