The mpich2 source package is getting build failures on the unofficial
Debian x32 port:

The attached debdiff fixes this by updating the test for i386 asm to
include these offending push/pop instructions.  It also updates the
test for x86_64 asm so it should pass on x32 as well (though in a
search I didn't actually find any x86_64 asm).

(Sorry the changelog from the debdiff is inaccurate -- I got autoconf
errors trying the dh-autoreconf route, which I couldn't resolved, so I
moved to patching configure directly but forgot to update the
changelog.)
