mips: use MIPS32 (instead of MIPS32R2) as the instruction set
This should widen compatibility a bit, so that older CPUs can also
execute programs built by TinyGo. The performance may be lower, if
that's an issue we can look into implementing the proposal here:
https://github.com/golang/go/issues/60072
This still wouldn't make programs usable on MIPS II CPUs, I suppose we
can lower compatiblity down to that CPU if needed.
I tried setting the -cpu flag in the QEMU command line to be able to
test this, but it looks like there are no QEMU CPU models that are
mips32r1 and have a FPU. So it's difficult to test this.
