relinking broken on macosx?

well, now that Peter's patches are in libtool, it appears to be working 
again on MacOSX -- however, for some reason it seems to be trying to 
relink some libraries (not sure why, library paths are coded into the 
lib already, there's really no reason to ever relink on MacOSX).

I'm trying to update the OSX port of KDE to use the new libtool for 
testing, and arts ends up dying like this:

Going into the flow/.libs directory, I see this:

---(snip!)---
libartsflow_idl.1.0.0.dylibU
libartsflow_idl.1.dylib
libartsflow_idl.dylib
libartsflow_idl.la
libartsflow_idl.lai
---(snip!)---

...you'll notice it looks like it's appending a "U" to the filename for 
some reason.  I can only assume that's either a bug in the first place, 
or it's some kind of intermediate file name that isn't getting renamed 
again after the relink.  Any ideas what's going on?
