PATCH: Update src/intl from gcc/intl

[Steve Ellcey]

DJ,

I have updated the intl directory to match the GCC directory so if you
could add that to your libiberty merge process that would be great.  I
also copied config.rpath over at the top level so that should be added
too.

If anyone runs into a problem with the new intl directory bits please
let me know and I will try to fix any problems that arise.
