[Buildroot] [PATCH 01/10] kconfig infra: support built-in config files

[Yann E. MORIN]

From: Thomas De Schampheleire <thomas.de.schampheleire at gmail.com>

When the configuration file of a package is located inside of the
package sources, a make dependency can only be expressed after the
package has been extracted (and patched).
