MIPS/LD/testsuite: Set architecture for MIPS16 HI/LO tests

Remove regressions across MIPSr6 targets with the MIPS16 HI/LO tests,
which are incompatible with the default architecture of these targets:

mips-img-elf  -FAIL: R_MIPS16_HI16 and R_MIPS16_LO16 relocs
mips-img-linux  -FAIL: R_MIPS16_HI16 and R_MIPS16_LO16 relocs
mips64-img-linux  -FAIL: R_MIPS16_HI16 and R_MIPS16_LO16 relocs
