Subject: include/package.mk: Add support for src-checkout/ folder
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=HEAD;p=openwrt%2Fstaging%2Fblogic.git

include/package.mk: Add support for src-checkout/ folder

This feature is similar to the SRC_TREE_OVERRIDE. However instead of having
to manually create a symlink inside the package folder, the buildsystem
will check if $(TOP_DIR)/src-checkout/$(PKG_NAME)/.git is present and use
this instead.
