  I think if you just use a .section directive with only a section name and no
flags, that ought to assemble everywhere.  Since it's an assembler-only test
that doesn't need a compiler, you can easily run a script that builds and
tests binutils for a whole huge list of cross-targets and see whether it fails
anywhere.  (I'll send you a copy off-list if you'd like.)
