The __set_errno macro _must_ match that defined in include/bits/errno.h. We
can't tack in the return -1 since then when people include errno.h, the return
-1 mysteriously vanishes... Setting the __set_errno back and restoring the
'return -1;' calls to each _syscall[0-n] macro makes mips syscalls work again.
