Disable o32 ABI for MIPS64 architectures 



Building o32 ELF files for MIPS64 is an exotic configuration that nobody
should be using. If o32 is required, then is better if it's built for
MIPS 32-bit cores so only 32-bit instructions will be used leading to a
more efficient o32 usage.

Support for MIPS o32 ABI on MIPS-64 targets has been removed. Building

o32 ELF files for MIPS64 is an exotic configuration that nobody should

be using. If o32 is required, then is better if it's built for MIPS

32-bit cores so only 32-bit instructions will be used leading to a more

efficient o32 usage.
