Except it is not a wise idea at all to add $(STAGING_DIR)/usr/bin to
PATH, because $(STAGING_DIR)/usr/bin contains binaries compiled for the
target. For example, if Python has been built, then "python" will be in
$(STAGING_DIR)/usr/bin, and because you put $(STAGING_DIR)/usr/bin in
front of everything else, the target-built python will be used during
the build process. Not good.
