Hello Michael,

I've only worked with the n32 ABI so far, so I'm not familiar with
the EABI nor o32 ABI. But I presume you know what you're talking
about :-).

I'm not sure I really have the knowledge to approve but Daniel asked
for help in that department, so I'll give it a try.
This patch seems pretty logical to me, so go ahead and commit. Is it
possible to run the testsuite on either o32, or on a target board?
Thanks,
