[Bug target/9468] [HP-UX] 3.2.1 ICE building libgcc muldi3.o when dwarf2 is enabled

The hppa2.0w-hp-hpux* and hppa1.*-hp-hpux* ports do not support the
dwarf2 debugging format.  DWARF2_DEBUGGING_INFO is only defined for
the linux and 64-bit hpux ports.  DBX_DEBUG is the default with gas.

--with-dwarf2 is not a valid configure option to use with the above
targets.  That's the main issue here.

I doubt gdb supports dwarf2 for this target.  If it does, it's not
well tested.  It does appear that gas has the support.

We would need named sections to support the dwarf2 format.  We removed
them a while back because there is no benefit from a code standpoint
and they created problems for the linker when we used secondary definition
symbols for weak symbol support.  There would be some benefit in having
dwarf2 EH support on this target but there are significant compatibility
issues as you can't support both sjlj and dwarf2 at the same time.
