Dear Aneesh V,

The decision should not be make in the top level makefile, but in
spl/Makefile.  And this can simply check if a board directory exists
in the first place.

Because then we need board specific directories and board specific
Makefiles even for those boards where no board specific code exists,
and all these Makefiles will be semi-identical copies of each other.

Having to maintain multiple copies of identical Makefiles is more
complicated and error prone in the long run. Let's rather spoend a few
thoughts initially and solve this problem before it spreads.

Best regards,
