0a129eb19a sim: hoist cgen mloop rules up to common builds
These rules don't depend on the target compiler settings, so hoist
the build logic up to the common builds for better parallelization.

We have to extend the genmloop.sh logic a bit to allow outputting
to a subdir since it always assumed cwd was the right place.

We leave the cgen maintainer rules in the subdirs for now as they
aren't normally run, and they rely on cgen logic that has not yet
been generalized.

65f42b88ff sim: tighten up stamp rules
Add a new ECHO_STAMP helper and convert existing stamp code over
to it.  This is mostly common rules and cgen mloop rules.

b6143d3162 sim: silence stamp touch rules
We pretty much never care about these stamp touches, so silence them.
Also switch to using $@ when it makes sense.

1bf5c34239 sim: unify cgen maintainer settings
Move these options up to the common dir so we only test & export
them once across all ports.  It makes it available to targets that
aren't cgen-based, but those will just ignore the settings, so it
shouldn't be an issue.

982c3a65ca sim: move -Werror disabling to Makefile
For the ports that still don't build with -Werror, rather than disable
the flag at configure time, do it at make time.  This will allow us to
unify these tests in the common sim configure script.

52d37d2c91 sim: drop arch-specific config.h
All of the settings in here are handled by the common top-level
config.h, so drop the individual arch-config.h files entirely.

This will also help guarantee that we don't add any new arch
specific defines that would affect common code which will help
with the effort of unifying them.

e7d8f1da71 Remove and modernize dependencies in sim
Some spots in the sim build used manual dependencies, and some spots
did a compilation by hand but did not use the automatic dependency
tracking code.  This patch fixes these spots.

I didn't touch ppc, because it doesn't use the common Makefile code.
I also didn't touch objects that are for the build machine, because
automatic dependencies don't work for those.
