We do it just because gcc in some distributions do it.
I can see why --build-id is useful for distributions, but given the
cost on day to day edit+build cycles, any distro using clang should
really just pass -Wl,--build-id in rpmbuild (or corresponding tool).
Even upstream gcc is not as aggressive as current clang. It has a
--enable-linker-build-id configure option and it defaults to false.
Cheers,
Rafael
