To make sure the project (and many linux specific libraries) builds on linux lets add a linux step to build for both musl and glibc. Eventually this will run unit tests as well.

Today there's quite a few things that do not compile if you change musl out for glibc. This is either due to type differences between what some of the syscall wrappers expect (enums vs. raw integers) or the fact that swifts glibc modulemap doesn't define gnu_source so some headers don't get included (vfs.h for statfs and pals). To work around this, we need to expose either compatability shims, or just expose the headers we need in our existing c shims we already have.
