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.
