The condition in syscall_defs.h is TARGET_MIPS, not TARGET_MIPS64.
They should match, despite the fact that it doesn't actually matter
for the 32-bit abis.

There's no reason to duplicate all this code. Yes, when someone wrote
this in the first place, they wrote separate sectons for each mips abi.
However, as you can see that huge portions of this block are identical,
this was obviously a mistake.
Start by changing the original section to #elif defined(TARGET_MIPS)
and see what needs changing specifically for the ABIs. I'm not even
sure there are any differences at all.
