For a new port, the best approach is to find the closest CPU
architecture that GCC has been ported to and clone that port.  That
means copying the gcc/config/FOO subdirectory and modifying that.

As for the details of the .md files and the like, I recommend you read
the GCC internals manual -- in particular, the chapter on machine
descriptions.
