Well, Alan sent patches updating libbpf to 1.5.0, so I misunderstood, I
think he meant what is to become 1.5.0, so even better, I think its just
a matter of updating the submodule sha:

⬢[acme@toolbox pahole]$ git show b6def578aa4a631f870568e13bfd647312718e7f
commit b6def578aa4a631f870568e13bfd647312718e7f
Author: Alan Maguire <alan.maguire@oracle.com>
Date:   Mon Jul 29 12:13:16 2024 +0100

    pahole: Sync with libbpf-1.5
    
    This will pull in BTF support for distilled base BTF.
