My use of "enabled" may not have been the best word choice since I
didn't mean to imply a kernel option.

I'm still using GENERIC on the 7.2 buildbot, so I didn't need to
recompile the kernel in that release either.  The issue was that the
POSIX semaphore module wasn't loaded by default (something I thought
only changed in 8.x), so the buildbot currently has a 'sem_load="YES"'
loader.conf entry to ensure that's done.
