rustc/cargo support any target for which a Rust stdlib is distributed, but you are left on your own to install and manage other software which will be needed to do the compilation such as a C cross-compiler for the target, etc. This is much more troublesome for some combinations of host/target than others. Personally, I have yet to get OS X --> Linux working, but Linux/glibc --> Linux/musl was pretty easy.
