Initial testing found the need for this due to the general check for the updated header search locations.  As reviews progressed with @tahonermann, it was suggested to not add the explicit header search locations as it was not determined yet (SYCL specific headers and libraries not yet part of the build) so now there is nothing being tested here for this target.  This can be cleaned up and added again later when the headers are actually searched.
