I observe the same problems for Solaris SPARC.  The problem is that 
GCC outputs paths which are not decorated for the specified 
architecture and libtool blindly uses them.  If libtool included a 
test for the architecture, then it could decorate the search paths 
with the subdirectory where the libraries for that architecture lives. 
On multilib systems, GCC itself automatically decorates the search 
path so that the correct libraries are used, but libtool circumvents 
this automatic support.  I think that the problem is a result of a GCC 
bug, but libtool needs to work with what it is given.
