0fa5e65b - [Stdlib][Build] Fix the standard library build for fully static Linux.

[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. rdar://123508245
