MIPS/GAS/testsuite: Force o32 for tests expecting 32-bit addressing

A few GAS tests expect to be assembled with 32-bit addressing, otherwise
causing an assembly warning:

.../gas/testsuite/gas/mips/fix-rm7000-2.s:11: Warning: la used to load 64-bit address; recommend using dla instead

or pattern dump mismatches against 32-bit address calculations, however
these tests do not enforce their expectation in any.  For none of them
the specific ABI used is of any relevance however, so select the o32 ABI
unconditionally, removing these failures with OpenBSD targets:
