Those tests were too simple, so a more robust technique was
introduced here:

    Fix defect exposed 20200402T1125Z: 'make' subtlety
    
    Variable assignments via $(eval include ...) take effect before
    recursive expansions on subsequent makefile lines, but not before
    immediate expansions and not before other makefiles are included.
    See commit 8b8a6608da8 of 20200402T1125Z for a demonstration.

The new technique is closer to the 'make' maintainer's
suggestion here:
