Currently, the python-host.mk framework relies on HOST_BUILD_PREFIX to refer to the $(STAGING_DIR)/host directory but using the HOST_BUILD_PREFIX variable requires the use of include/host-build.mk which in turn includes python-host.mk, leading to target redefinition errors. In order to provide a global, uniform way to refer to the host staging directory, LEDE introduced a new variable STAGING_DIR_HOSTPKG which points to $(STAGING_DIR)/host for now with the purpose of eventually being able to relocate that directory in the future. This commit changes python-host.mk to ... - stop including include/host-build.mk (revert of #3423) - replace usages of $(HOST_BUILD_PREFIX) with $(STAGING_DIR_HOSTPKG) - warn and fallback to $(STAGING_DIR)/host if STAGING_DIR_HOSTPKG is unavailable The fallback code will ensure that the python host build infrastructure continues to work properly on older OpenWrt and LEDE versions until the STAGING_DIR_HOSTPKG is fully settled in and can be removed some time in the future.
