Hi Peter,

Yes, that idiom to remove the "try to fake it" from ltmain.sh is 
generally valid for cross-compiling systems.  There are many issues 
related to libtool and cross-compiling, but it's safe to say as a guide:

* Don't install _any_ .la files to the rootfs (target NFS area)
* You may need to add:
  perl -pi -e 
's,^sys_lib_search_path_spec=.*,sys_lib_search_path_spec=,' libtool
  after ./configure ... in .spec file %Build sections
* You may need to comment out  the "try to fake it" -L/usr/lib section 
from ltmain.sh

BTW: Thanks for sharing your changes to Ubuntu, I think they'll be 
helpful to others.
