[PATCH 0/4] linux-user: Support o32 ABI with 64-bit MIPS CPUs

[Philippe Mathieu-Daudé]

This series allow building linux-user emulator to run ELF
binaries built for the MIPS o32 ABI on 64-bit CPUs (binaries
produced by Sony Linux Toolkit for Playstation 2 for the
R5900 CPU).

The new QEMU binary is named 'qemu-mips64o32'.

The binfmt config isn't correct, as it matches mipsel/mipsn32el.
I missed to understand how mipsel (o32) and mipsn32el (n32) are
differenciated.

Based-on: <20201119160838.1981709-1-f4bug@amsat.org>
