2 DJGPP-specific files: in distro or only in DJGPP package

[Tim Van Holder]

I'd like to add a djgpp subdirectory containing 2 files: a
README for the DJGPP port, and a config.site for use on
systems running DJGPP.  Other files may be added later.
Is it allowed to add these to the official tree, so they end
up in the release tarballs, or should these only be part of
the DJGPP package?
