No cc commands get run to link (output below).  Libtool has decided that 
it couldn't satisfy all inter-library dependencies for the module (even 
though the only dependency is a single libtool convenience library), and 
is hence building a static archive using ar and ranlib.

The .a archive is obviously not a bundle library, hence it spits the 
error.
