Any reason to not use the PA 2.0 ISA? I'm virtually certain we
supported the 32bit ABI running on PA 2.0 hardware in hpbsd (which is
where the netbsd PA code is ultimately derived from). I'd be really
surprised if there's any PA1.1 hardware running anywhere, though there's
certainly some PA2.0 hardware out in the wild.

You probably don't need dbxelf.h. Embedded stabs should be avoided when
it can be.
