I think if $(words $(PATH_TO_CHECK)) is 1, then it's OK and if it's >1
then it contains whitespace.

You can write a test using $(if ...) rather than using ifeq, then it
can be put anywhere:

  $(if $(filter-out 1,$(words $(PATH_TO_CHECK))),$(error spaces found))

Just to note this will also say "spaces found" if the variable is
empty... you'll have to check that separately if it's something to be
concerned about.
