kgdb: depends on VT
With VT=n, the kernel build fails with:
drivers/built-in.o: In function `kgdboc_pre_exp_handler':
kgdboc.c:(.text+0x7b5aa): undefined reference to `fg_console'
kgdboc.c:(.text+0x7b5ce): undefined reference to `vc_cons'
kgdboc.c:(.text+0x7b5d5): undefined reference to `vc_cons'
kgdboc.o is built when KGDB_SERIAL_CONSOLE is set. So make
KGDB_SERIAL_CONSOLE depend on HW_CONSOLE which includes those symbols.
