When building libc crate with musl, don't look for libc.a

Browse source 
musl may not be available on the target user's machine, and even if
it is, we may not be able to find it because of how static libraries
are searched for.
Instead, use the transitively included liblibc which includes libc.a.

// When compiling rust with musl, statically include libc.a in liblibc.rlib.
// A cargo build of the libc crate will therefore automatically pick up the
// libc.a symbols because liblibc is transitively linked to by the stdlib.
