The above allows the average user to just type "make menuconfig"
and then the configuration of the current kernel is presented to
the user. This is convinient in many cases.
We know the /proc/config.gz is an incresingly popular way to gain
access to the configuration of the running kernel. So extending
the already know and working way to obtaing the configuration
of the running kernel to suppport /proc/config.gz is logical.
The fact that the configuration is gzipped does not warrant
a new option to deal with this that almost duplicate the
existing functionality.
