I just posted a patch with the subject of "[PATCH python] define
__GNUC_PREREQ macro before using it" [1]. Give it a shot and let me
know if that fixes the issue.

Additionally, if you can potentially provide a FreeBSD machine that we
can use as a BuildBot [2] for libvirt-python, that would likely
prevent problems in the future. You can see the BB here [3].
