Seems we have a few options for making threaded libpq on Unixware:
o  remove thread-safe SIGPIPE code, which calls thread library
o  create a threaded and non-threaded libpq library
o  add a libpq function that enables threading, and do dynamic
linking of thread calls based on that function
o  Add thread flags to all builds on that platform, including
the backend
o  Add the ability to specify compile/link flags for everything
but the backend

As I remember, libcrypt used to be required by all libpq builds on
various platforms.   This seems to be a similar case.

I think the last option might be the best.  Somehow create different
cppflags/libs for the backend and non-backend programs.
