As far as I know, uClibc does not implemnt the AIO part of POSIX. Is
there perhaps any way to make iozone use some fallback in place of
AIO? It's not like POSIX AIO is a particularly well-designed API that
anybody would actually WANT to use...

If there's really no way around it, you could see if someone could
help you getting AIO added to uClibc.
