This allows checking e.g. stdenv.hostPlatform.isGnu, just like isMusl or isUClibc. It was already possible to check for glibc with stdenv.hostPlatform.libc == "glibc", but when that doesn't line up with how every other platform check works, this is apparently sufficiently non-obvious that we've ended up with stuff like adding glibc.static if !isMusl, which is obviously wrong.
