Hi,

j-a-c-k FTBFS on hppa.  While some of the issues may be buildd related,
some of them aren't; the good news is that I believe I've fixed them. :-)
(at least, I've successfully built j-a-c-k on the hppa porter box)

There are two issues:

- waf's parallel building and hppa don't mix; I've stolen a patch which
Jakub Wilk provided for xmms2 and applied it to j-a-c-k. It will break if
anything causes the .waf.-* directory to be renamed, but that seems like
another reason not to use waf ;-)

- the "alpha/ia64 segv fix" patch also needs to include hppa in its
growing list of architectures on which not to execute the relevant code;
the patch probably also wants renaming :-)

I've attached a new patch to fix the first; I assume the second is trivial
enough not to need a patch.

I'd appreciate an upload containing these changes so that we can hopefully
finally get j-a-c-k built on all architectures which are relevant for
testing migration.

Regards,

Adam
