With mips architecture, 64-bit programs cannot call o32 system calls.
For example, __NR_stime, __NR_socketcall, __NR_time, etc.
Better solve the problem described in commit: 22c2c9e2f

@Thomas or somebody from MIPS folks, could you please confirm this?

Merged your fix and reverted 22c2c9e2f, which is not needed now.
