This is relatively weird, especially, since they do have upstream commit
that try to make it work on "old CPUs":

    a5d126c61cc0  configure: fix avx512 check for i386
    f01d4b7a601f  mpi/longlong.h: i386: use tzcnt instruction for trailing zeros

So maybe this is a bug that should be reported and fixed upstream?

Yann E. MORIN.
