Fixed DASH bug when changing banks; the debugger didn't recognize the change, 

and hence didn't re-disassemble.

Fixed long-standing bug in the debugger disassembly; addresses marked as $F000
(or equivalent) were never being highlighted in the disassembly view.

with certain bankswitch types. The bankswitch UI should now be used
to query/set bank state.
* Fixed bug in disassembly output; instructions at $F000 were never
being highlighted during execution.
* The UNIX configure script now supports newer versions of Hurd.
Special thanks to Stephen Kitt for the patch.
