Agreed. I'm sure ARM will support 64-bit someday, so the "right" fix
would be to change gcc to make -m32 a no-op for ARM and other
32-bit-only targets, but I'm assuming that approach would be...
onerous. ;-)

That sounds valuable, but I take homegrown to mean not suitable for
general inclusion? My patch is not nearly so ambitious.

Done: HADOOP-7276. I linked it to your GNU-ness issue (though I'm
guessing JIRA probably told you that already).

FYI, I just noticed that Hadoop "one button cluster install" is a goal
for the Ubuntu ARM Server release for 11.10
so expect a few more patches. ;-)
