Second that. This patch needs a proper commit message anyway, I don't know how 
it managed to arrive to this list without one.

I do know the answer to the connection between this patch and nanoMIPS though. 
nanoMIPS supports different set of syscalls from "stat" group than 
mips32/mips64/mipsn32 or any other platform. Without this patch, nanoMIPS QEMU 
user-mode build would fail (but complete nanoMIPS QEMU user-mode support have 
not been sent for review to this list so far - it will be sent most likely next 
week).
