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

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.
