clang: Stop implicitly passing -Wl,--build-id to the linker.

We explicitly pass that in official builds now, and after we've built and
rolled in a compiler with this change here, we'll no longer ask the linker
to generate a build id in unofficial builds (where it's not needed), which
should speed up links a bit.
