core: Add a phony package definition This allows one to declare a meta-package that depends on a list of modules. This is extremely useful for vendor provided prebulit libraries where there is a big list of libraries/binaries to include. Specifying that list in multiple places would be error prone and eventually lead to very annoying bug hunts. With a fake package, one does: LOCAL_MODULE := my_fake_package LOCAL_REQUIRED_MODULES := <list of required module names> LOCAL_MODULE_TAGS := optional include $(BUILD_PHONY_PACKAGE) Change-Id: Idcfe91f6f2d6d886aba094981a70690e5a808bfc Signed-off-by: Dima Zavin <dima@android.com> 2010-09-16 09:25:16 +02:00			`LOCAL_MODULE_CLASS := _FAKE_`
