How about instead of adding it to every simulator,
just add it as a common piece of code that gets linked in with
<target>-run and turned on when some argument is passed.

OTOH, is all one would end up doing is copying a bunch of code
from gdb/gdbserver to sim/common?

[That's an honest question.  Just trying to learn how you require it.]
