hpux11 support


This is for the mainline tree only.  Threads did not work last I checked, but
I was not using an official hpux11 release.

I would greatly appreciate it if any interested party tested the hpux11
thread support on an official hpux11 release and let me know if it works.



	* configure.in (hppa*-hp-hpux11*): New configuration.
	* configure: Rebuilt.
	* pa/pa-hpux11.h: New file.
	* pa.h (CPP_SPEC): Conditionally add -D__STDC_EXT__ to the cpp
	command line.
