we have run into a problem where package developed on Debian and packaged for 
Fedora had rpath included in binaries. This is bad and forbidden by rpm rules 
(rpmlint will mark it as an error).

After long discussion with upstream and Fedora packagers mailing list we have 
found a reason for this bug: libtool does not consider "/usr/lib64" as default 
location for libraries. On Fedora for x86_64 it's however default location for 

We would kindly ask you to incorporate patch to add "/usr/lib64"  as default 
location for libraries to the official source code.

This will enable packages developed on other than Fedora systems (with 
included libtool script) to be compiled properly on Fedora.

Thanks a lot!

Well, actually the upstream libtool (Fedora uses 2.2.6a) does not take
care of /usr/lib64 for rpath (and this seems the same for the latest 2.2.8).
What I usually say is that:
     - Usually the reason that unneeded rpath /usr/lib64 is added to
       the rebuilt binary is that the upstream developer uses libtool
       which does not take special care of /usr/lib64 for
       sys_lib_dlsearch_path_spec, while Fedora's libtool take care of
       this by adding a patch. See the below patch:

       So actually for most cases, the case that rpath /usr/lib64 is added
       (only for 64 bits arch) can be avoided by
sed -i.libdir_syssearch -e \
   '/sys_lib_dlsearch_path_spec/s|/usr/lib |/usr/lib /usr/lib64 /lib /lib64 |' 
       i.e. just add the needed paths to sys_lib_dlsearch_path_spec in
       configure (note that libtool in the build directory is generated by
       configure) before calling %configure.
       - You can alternatively do "autoreconf -fi", however calling autotools
         is not recommended unless unavoidable.

So it is highly possible that if the upstream does not use Fedora (i.e. does 
use patched libtool) rpath /usr/lib64 appears on Fedora.
And I just confirmed that this method works for this package (hwloc).
