Hi Tom. I don't believe selftests is linking. The reason I included it in the
BuildRequires for selftests is that I thought that selftests was running the
systems feature check that included llvm. (The feature check for llvm
(`tools/build/feature/test-llvm.cpp`) requires headers from the llvm-devel
package.) But after taking a another look, I was wrong, I don't believe
selftests is running the system feature check. I'll make the change and
include this package only for bpftool.
