Alastair Houghton 0fa5e65bb2 [Stdlib][Build] Fix the standard library build for fully static Linux.
Mostly this just means adding `Musl` as a module dependency of various
things and making sure that we build things for `swift_static` even
if `SWIFT_BUILD_STATIC_STDLIB` isn't enabled.

There's also a slight difference in the declaration of `memcmp()`;
musl's declaration is more like the one we have on Darwin.
