Mike Frysinger 36bb57e40c sim: drop configure scripts for simple ports
These ports only use the pieces that have been unified, so we can
merge them into the common configure script and get rid of their
unique one entirely.

We still compile & link separate run programs, and have dedicated
subdir Makefiles, but the configure script portion is merged.
