Remove precompiled binaries

Recently https://musl.cc has blocked all traffic coming from Github
actions, so I can not precompile these binaries automatically anymore. I
empathize with the toolchain maintainer's plight. I can not get these
binaries to be mirrored in Github so that the bandwidth stays in house.
Nor do I want to be building on my home machines manually.

Instead, this will go back to being compiled from source for everyone.
