[PATCH 3/4] default-configs: Support o32 ABI with 64-bit MIPS CPUs

2020-11-19 Thread Philippe Mathieu-Daudé
MIPS o32 ABI on 64-bit CPUs looks like a ILP32-on-64bit data model, allowing 64-bit arithmetic and data movement instructions. This is the default ABI used by the "Sony Linux Toolkit for Playstation 2". As we don't know big-endian uses, we only introduce the little-endian variant. Inspired-by:
