Fix detection of MIPS32 (#655)

Browse Source 
_ABI64 and _ABIO32 are always defined on every
Linux MIPS system, at least if it's glibc-based:

https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/mips/sgidefs.h;h=c9e00c6da53b1a13d83b4056f01ef5c30efe76ab

The correct way to use them is to compare them
against _MIPS_SIM symbol provided by the compiler.

With this change, engine correctly detects 32-bit
MIPS systems.
