The code is attempting to allow something like:

./libtool --mode=link --tag=CC cc -o libfoo.la ./a/libbar.la ./b/libbar.a

where you have two different convenience libraries with the same 
basename. Because they're convenience libraries libtool should ensure 
that all objects in the archives end up in the output, so it renames one 
and adds all objects from both convenience libs.

In your case the same convenience archive ended up on the link line 
twice by accident, libtool doesn't check for that, I'm copying 
bug-libtool to create a bug report for this, thanks.
