Add an option for Waiting for gdb connection if the gdb stub configuration is chosen.

Here's a quick demonstration on how to use it(tested on M4A785T-M).
      (gdb) file ./build/cbfs/fallback/coreboot_ram.debug
      Reading symbols from [...]/build/cbfs/fallback/coreboot_ram.debug...done.
      (gdb) set remotebaud 115200
      (gdb) target remote /dev/ttyUSB0
      Remote debugging using /dev/ttyUSB0
