Well, in fact that did not work. See gharial: it appears to have picked
the wrong thread flags.
And even more annoying, now that I've git pull'd, I find it's also broken
the build on my RHEL6 box:

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.
I'm debugging this ATM. You're probably seeing a failure similar to
shearwater. The problem seems to be that the earlier autoconf tests add
"-lrt" to LIBS, and that somehow pulls in pthread_join() and other
functions, but not pthread_sigmask(), even when not compiling with -pthread.
I'll dig a bit deeper, but I think that could be fixed by moving the
AX_PTHREAD call in the configure script earlier, or by temporarily
clearing LIBS before calling it.
