We dropped support for ia64 host CPUs in the 2.11 release (removing
the TCG backend for it, and advertising the support as being
completely removed in the changelog). However there are a few bits
and pieces of code still floating about. Remove those, too.
We can drop the check in configure for "ia64 or hppa host?"
entirely, because we don't support hppa hosts either any more.

You could in theory have before this commit tried to still use ia64
hosts with the TCI interpreter, but there's no point in supporting
ia64 hosts with TCI but not proper TCG.
The next bit of cleanup I'd like to do after this is get rid
of the "uname -m" fallback in the configure cpu-detection code...
