There's no rule saying that libc must pass on all of the RT signals
to the application program.  

While I would have preferred POSIX to define a set of rt signal number
allocation functions (as glibc snapshots now do), we can simply grab
two for pthreads use and define SIGRTMIN & RTSIG_MAX to avoid them.
