We are in the process of getting a CI set up to test the binutils/GCC
support for the kernel BPF selftests [1].  We are told they need
tarballs.

Having this CI is very important to us due to the fragile nature of
compiled BPF.  Without it any update to the kernel BPF selftests can
potentially break the build with GCC.
