Without any of my patches, GMP 4.1 builds fine on HP-UX 10.20 and
11.00 (--host=hppa1.1-hp-hpux10.20) with one error. So, ignore my
configure.in patch. If you want to remove the errors above, the
".level 1.1" patch to the asm files needs to be added.

This test passes when I don't force --host (i.e. building a PA-RISC
2.0 binary -- hppa2.0n-hp-hpux10.20).
