Adjust configure to use "+Olibmerrno" with HP-UX C compiler, if possible.
This is reported to be necessary on some versions of that OS. In service
of this, cause PGAC_PROG_CC_CFLAGS_OPT to reject switches that result in
compiler warnings, since on yet other versions of that OS, the switch does
nothing except provoke a warning.
Report and patch by Ibrar Ahmed, further tweaking by me.
