And even more annoying, now that I've git pull'd, I find it's also broken
the build on my RHEL6 box:
../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_sigmask'
collect2: ld returned 1 exit status

It appears the new improved macro doesn't bother with -pthread at all.
Previously I got this in Makefile.global:
PTHREAD_CFLAGS = -pthread -D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS
PTHREAD_LIBS = -lpthread
Now I get
PTHREAD_CFLAGS = -D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS
PTHREAD_LIBS =
and that simply doesn't work. I do not know why the buildfarm isn't
entirely red, but I'm dead in the water. Please revert this.
