sim: testsuite: punt unused toolchain variables

These haven't been used in over 20 years.  The sim testsuite used to
run these tools itself directly, but back in ~1999 it switched to the
dejagnu helpers (e.g. target_assemble & target_link), and the dejagnu
logic only utilizes XXX_FOR_TARGET variables.  Punt them here to avoid
confusion with dead code.
