[Buildroot] [PATCH 1/4] package: enhance infrastructure to support source dir override

[Alper YILDIRIM]

Hello Thomas,

We started using your "source override" patches, but we encountered a
problem.
Package dependencies are not build when a package source is overriden. 
To overcome this problem we made the following change in Makefile.package.in

ifeq ($($(2)_OVERRIDE_SRCDIR),)
$(1)-configure:		$(1)-patch \
			$$($(2)_TARGET_CONFIGURE)
else
$(1)-configure:		$(1)-symlink \
+                      $(1)-depends \
			$$($(2)_TARGET_CONFIGURE)
endif

$(1)-symlink:		$$($(2)_TARGET_SYMLINK)

Cheers,
Alper
