--- Comment #7 from Kubilay Kocak <koobs at FreeBSD.org> ---
I believe a more correct way scope this block would be to check whether the
compiler supports the flag before using it, rather than using the gnu compiler
check macro. 

There is an ac_check_compile_flag macro in the autoconf archive [1] that does
this. 

This should be reported and submitted upstream at libffi, and then in Python to
improve 2.7-3.6. Local patches of these upstream patches could be carried if
necessary (if they fix actual issues caused by the bug) in the FreeBSD Ports
until newer versions or libffi/Python are released.
