No, it's going to break every place that the conf file "knows"
it's FreeBSD, and spews out -pthread into the generated Makefile's
from the Makefile.in, because it "knows" that FreeBSD has -pthread.

This is going to have to be changed on an application-by-application
basis, since the damn thing is recognizing the platform, rather than
the platform capabilities.

Pick 10 autoconf-using, threads-using ports at random, and go into
the platform support subdirectories, and note that the FreeBSD
entry has explicit settings for using -pthread.
