Start adding support for Musl.
The two patches together enable clang to support targets like
"x86_64-pc-linux-musl" and build binaries against musl-libc instead of
glibc. This make it easy for clang to work on some musl-based systems
like Alpine Linux and certain flavors of Gentoo.
Patch by Lei Zhang.
