config.rpath origination?

[Karl Berry]

At the beginning of the config.rpath that is checked into the savannah
gnulib project (included below), it says "from gnu libtool".  But I
don't actually see any file named config.rpath in the libtool 1.4.2
distribution (although the code is actually present in several different
places within libtool).

So my question is, is there some way we can get the "ultimate source"
for config.rpath out of libtool?  Or should we consider the one in
gnulib as the ultimate source?  Or ... ?  It seems unlikely to me that
this code hasn't needed to be changed in the last year or two.

Just trying to figure out how to keep things in sync.  Not a huge issue.

Thanks,
karl

Here is the config.rpath that is currently in gnulib.
