  Hmm.  Perhaps a better solution than a config variable would be
to record the old value of the VBR register in trap_init() and
use that for stub trap delegation?  This should work on any system
and not need the user to figure out where his system's gdb VBR
table is loaded.  I can work up a patch for this tomorrow.
