[PATCH 2/2] Makefile: let header dependency checker override COMPUTE_HEADER_DEPENDENCIES

This way, if you have “COMPUTE_HEADER_DEPENDENCIES = YesPlease” in your config.mak, you can still “make CHECK_HEADER_DEPENDENCIES=Yes” to check the makefile after a successful build.

This change does not affect the result of the command “make CHECK_HEADER_DEPENDENCIES=Yes COMPUTE_HEADER_DEPENDENCIES=Yes”. That will still die with an error message:

	cannot compute header dependencies outside a normal build

The message is appropriate because still true.
