Whenever you have the need to "patch" the path in a Makefile, you can do that with the following line.

PATH := $(PATH):/optional/path

Use $(PATH) to get the PATH variable from the environment. := is used to avoid circular dependencies in the form, that PATH gets reassigned over and over again. If you leave the colon, then make will inform you about this.
