Move these options up to the common dir so we only test & export
them once across all ports. It also enables -Werror usage on the
common files we've been pulling out of arch subdirs.
This provides a space to generate things that we only need to build
once per-arch. Some day that will be all of common/, but for now,
we move the version.c management in.
The igen build fails for me like:
gcc -g -O2 -c ../../binutils-gdb/sim/igen/igen.c -o igen/igen.o
In file included from ../../binutils-gdb/sim/igen/igen.c:26:
../../binutils-gdb/sim/igen/lf.h:22:10: fatal error: ansidecl.h: No such file or directory
This patch fixes the problem by arranging for igen to find the
libiberty includes.
This seems slightly hacky to me, because libiberty is not a "build"
library, so it can't be linked against. However, since igen currently
only includes the header, it seems relatively safe.

* Makefile.in: Rebuild.
* Makefile.am (AM_CPPFLAGS): New variable.
Now that we have the common automake build with support for build-time
programs working, we can integrate the common tests into the default
`make check` flow.
This doesn't actually create one `run` program like other projects,
but creates multiple `run-$arch` targets. While it might not seem
that useful initially, this has some nice properties:
- Allows us to quickly build all sim targets in a single tree.
- Positions us better for converting targets over to a proper
multitarget build+install.
We don't have the ability to actually run tests against them, but
that's due to a limitation in gas: it doesn't support multitarget.
If that ever changes, we should be able to turn on our tests too.
We can improve the test framework to fallback to a system toolchain
if available to help mitigate that.
This simplifies the build a bit (especially for deps in port subdirs),
and avoids recursive make. This in turn speeds up the build, and sets
us up for multi-target.
