This won't link librt on musl, is it correct behavior? (Moreover, any build with the std also won't link librt but it seems fine?:

libc/src/unix/mod.rs

Lines 302 to 304 in 90aa0e3

	} else if #[cfg(feature = "std")] {
	// cargo build, don't pull in anything extra as the libstd dep
	// already pulls in all libs.

)

librt.a of musl is empty file:

> cat /usr/lib/librt.a
!<arch>

And build of libc with std feature will pull std and a prebuilt libc with rustc-dep-of-std feature

Thanks for clarifying! Then it should be fine. There're still some uses of name = "rt", I think they all also can be removed, right?
Anyway, this is good to go as-is, let's r+ :)
