I've tried the same, modulo some paths. I'm pretty sure it's version
related at this point.
The current issue I'm seeing is "error: indirect call in function,
which are not supported by eBPF" when using GCC-BPF for
progs/bind4_prog.c

Currently using clang 16.0.0 and gcc 12.2.0-14.
I did manage to get it to build by just commenting out TEST_GEN_PROGS
+=3D test_progs-bpf_gcc
