Christophe Bothamy 052ee134b7 - fix [ 629606 ] BX_WITH_TERM affects ^C handling : 
. if BX_GUI_SIGHANDLER is true and the term gui is selected at run time,
    a new global boolean (bx_gui_sighandler) variable is set to true.
    Special signal handling is done if bx_gui_sighandler is true.
  . if BX_GUI_SIGHANDLER is not true, bx_gui_sighandler is not compiled in.
