sim: use AM_MAINTAINER_MODE

I noticed the sim code is using an old implementation of the maintainer logic.
I cut it over to the new macro (like gdb has been doing).  In practice, it
makes no difference currently as nothing in the sim tree uses it, but I have a
follow up commit for the Blackfin tree that needs it.
