Move the various platform tests up a level to avoid duplication
across the ports. When building multiple versions, this speeds
things up a bit.
For now we move the obvious stuff up a level, but we don't turn
own the config.h entirely just yet -- we still have some tests
related to libraries that need consideration.
The sim's recently switch to using Automake caused a build failure for
me, because I didn't have the correct auto* tools in my path.
However, the rule in the tree is that this is not needed in general.
This patch adds a call to AM_MAINTAINER_MODE, to align the sim with
the way the rest of the tree works here.
