There is no way to extend the trace mode bounds from a Portfile.

Files inside ${prefix} not provided by any port may be accessed, but not
outside ${prefix}. This is a workaround to allow access to cache files
such as the XML catalog or the GTK icon cache.

If these ROM files for the build are not distributable, how can the
result of this port be distributable under a GPL-2 license? That would
imply that the ROM does not end up in the build results at all.
