On 32-bit mips (ABIO32) _ABI64 is not defined and build fails if Wundef is used.
Problem could be resolved by including <sgidefs.h> header (which includes ABI definitions) into "_linux.cfg" file.
Another way to solve the problem could be changing "#if _MIPS_SIM == _ABI64" expression (if defined _ABI64 has value 3).

> $ gcc -dM -E -mabi=64 - < /dev/null | grep --color -s "ABI"
> #define _ABI64 3
> #define _MIPS_SIM _ABI64
