[PATCH 2/2] deb-pkg: add source package

[riku.voipio@linaro.org]

From: Riku Voipio <riku.voipio@linaro.org>

By passing BUILD_SOURCE=y variable, make deb-pkg builds a debian source
package. It will generate a minimal debian/rules file that calls back
to make deb-pkg. Generated source package will build the same kernel
.config than what was available for make deb-pkg.

The source package is useful for gpl compliance, or for feeding to a
automated debian package builder.

Patch depends on the "deb-pkg: move setting debarch for a separate function"
for correct changelog filenames.
