Thomas Petazzoni 8eb8aaf904 core: allow external Config.in/makefile code to be integrated ... This commit allows the BR2_EXTERNAL directory to contain Config.in and Makefile code, which gets integrated into the Buildroot build logic: - Buildroot automatically includes the $BR2_EXTERNAL/Config.in in the top-level configuration menu. - Buildroot automatically includes the BR2_EXTERNAL/external.mk in the build logic, so it can for example be used to include other .mk files that define package recipes. This is typically intended to be used to create target packages in the BR2_EXTERNAL directory, but can also be used for bootloaders, host packages, or other custom make logic. We also add a dummy Config.in file in support/dummy-external/ to ensure that the source "$BR2_EXTERNAL/Config.in" line will point to an existing file even when BR2_EXTERNAL is not used by the user.
