I'm not sure this should be an error; we allow debugging a main
executable whose architecture does not match the target architecture
(if the user knows what they're doing), so IMO we should allow this
for shared libraries too.  A *warning* would be more appropriate.

Also, I think it would be good if the message mentioned the architecture
in question, along the lines of:

  warning (_("`%s': Shared library architecture %s is not compatible "
             "with target architecture %s."), found_pathname,
           bfd_get_arch_info (abfd)->printable_name, b->printable_name);

Bye,
Ulrich
