sim: stop configuring common subdir

Now that cconfig.h doesn't exist, there's no need to build in the common
subdir anymore.  We leave the configure/Makefile files in there as there
is a helper for developers to generate the nltvals.def file.  Once that
gets cleaned up in the future though, we can drop the build logic too.
