Kernel build of commit 324c92e5e0ee are failing for me with this error

libbpf: relocation against STT_SECTION in non-exec section is not supported!
What information can I provide to help debug this failure?
Can you please send that bind_perm.o file? Also what's your `clang
--version` output?
clang version 12.0.0 (Fedora 12.0.0-2.fc35)
I suspect this might be due to Clang commit 6a2ea84600ba ("BPF: Add
more relocation kinds"), but I get a different error on 324c92e5e0ee.
So meanwhile you might try applying 9f0c317f6aa1 ("libbpf: Add support
for new llvm bpf relocations") from bpf-next/master and check if that
helps. But please do share bind_perm.o, just to double-check what's
going on.
Here is bind_perm.o: https://fedorapeople.org/~tstellar/bind_perm.o
