The n32 and n64 variants in ld-mips-elf/comm-data.exp fail assembly:

In ld.log:
Assembler messages:
Error: -march=mips32r2 is not compatible with the selected ABI
Assembler messages:
Error: -march=mips32r2 is not compatible with the selected ABI

Looking at the source, the mipsisa32r2 in the target triple is taken as the
default for the -march option, and "64-bit registers" are required.  I verified
a simple fix is adding a proper -march option to the test-cases for the 64-bit
variants.  Patch to be posted.
