The Makefile tries to generate both -32 and -n32 shared libraries. It
needs to do this so that smbwrapper will work with both older and new
binaries. 

I'm not sure quite what the best way to handle this is. Maybe
configure should test if -32 works and if not then don't try to build
the old 32 library.
