MIPS o32 ABI on 64-bit CPUs looks like a ILP32-on-64bit data
model, allowing 64-bit arithmetic and data movement instructions.
Since this ABI seems to have only ever been used for the
development of the PS2 with the "Sony Linux Toolkit for
Playstation 2" targetting the R5900 CPU (little-endian),
we name this user-mode target 'r5900o32el'.
