I posted a patch to BZ that should disable <semaphore> entirely for AIX 
(and other targets where there's not a supported implementation 
strategy).

This patch isn't the best way of addressing this for a variety of 
reasons, but this support is intended as experimental for GCC11 anyway. 
Unfortunately I can't test it on AIX because it would seem that my ssh 
keys never landed on the AIX cfarm machines.
