Try the current development sources.  I've made an effort in recent
months to make the shared library support buildable in a cross debugger
setting.  (If you still have problems with it, please let me know.)

See http://sources.redhat.com/gdb/#download for information on how
to get the current development sources.

Yes.

You're already doing it right.  I just did a test build for your target
using the current development sources and it worked fine...
