I perused the docs already without coming up with a satisfactory
solution.

What you can do is combine variables in the following way:

ifeq ($(foo)$(bar),yes)
  [ ... ]
endif

This will work if either foo or bar are set to yes, resulting in an
exclusive or operation.  If you are looking for a non-exclusive or

ifneq ($(foo)$(bar),)
  [ ... ]
endif

will trigger if foo or bar is set to yes (or both).

Of course all of this breaks with no values, but that shouldn't apply in
our case...
