OK. I don't know what MMO is.  I think mmix-* tests are disabled due
to `proc is_elf_format` (binutils/testsuite/lib/binutils-common.exp)



test_pattern="$1"
srcdir="${2:-$(cd "$(dirname "$0")" && pwd)}"
buildroot="${srcdir}/out/cross"
jobs="${JOBS:-$(nproc)}"

# Every architecture referenced in elf.exp, mapped to a concrete
--target triplet.

I noticed that RUNTESTFLAGS="elf.exp=${test_pattern}" did not properly
skip some tests, so I created
