linux-yocto: export kernel configuration audit to the console

Fixes [BUGID #692]

Previously the information dumped by the kernel configuration audit
scripts was only placed in log files. This isn't as useful as it
could be, since they are rarely checked. This change takes the
output from kconf_check and explicitly displays it to the user.
