Revert "Added local directory as source of kernel code"

Browse Source 
This reverts commit 73da2ff6f7.

The reason for adding support for a local location was to be able to do
development on the Linux kernel source tree on a local directory rather
than have to clone it for every build.

We already have a mechanism for that, it's called override-srcdir. It's
been available since September 2011, more than a year before this patch
was committed.

Otherwise, we're going to be adding support for local sources in other
packages. First was U-Boot as submitted by Adam. But what next? We can't
have such support for all packages, especially since override-srcdir
does the job.

Besides, using a local source tree makes the build non-reproducible, so
we don't really want to have this in a .config (or defconfig).

We only handle the boolean option in legacy, as there is nothing we can
do with the directory path.

The option to select a local directory as the source of the Linux
kernel has been removed. It hurts reproducibility of builds.
In case you were using this option during development of your
Linux kernel, use the override mechanism instead.
