__debug_octave__.m: Use slight more generic terminal on Linux.
* __debug_octave__.m: Eliminate unused return value from system().
Remove FIXME note about portable terminal on Linux. Use 'x-terminal-emulator'
as terminal default on Linux. Execute system() with "async" option so that
Octave and gdb can run separately.
