Already xfailed for mips.  You may want to check history to see if it's
applicable to xfail on hppa as well.

I just noticed that this bug may have been recently fixed.  Test
didn't fail on last hppa2.0w-hp-hpux11.11 build.

Need to check whether it is also fixed on linux.

Looking at history, I didn't get a clear answer as to whether xfail 
should apply to hppa as well.
