Build rust for other architectures supported by musl libc

Hello everyone! I see tendency to rewrite most things in rust language, I'm not against this everything is cool except the one thing... I've seen you folks made builds it for x86_64-musl and aarch64-musl and it's definitely better than nothing, but can you do them for 32-bit arm, mips, powerpc and others like you do on glibc?
