PATCH: KDB support without CONFIG_VT

[Juan J. Quintela]

Hi
        This patch makes KDB compile indeed if CONFIG_VT is not
        defined in .config.  That is quite useful for people that have
        headless machines and only compile the console driver to be
        able to use kdb.

Later, Juan.
