I've been tracking down when "umulditi3" support was added to various
gcc platforms. So far, I've found:

ia64: 2005-07-28, gcc 4.1.0
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=102463

mips: 2008-06-09, gcc 4.4.0
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=136600

alpha: 2013-02-01, gcc 4.8.0
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=195668

s390: 2011-10-07, gcc 4.7.0
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=179647

ppc64: 2013-02-01, gcc 4.8.0
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=195667


Here's a revised s390 patch.
