Good idea taking the address of the function since calling it would have
generated an error. Such a good idea actually, that I'm now wondering if
dropping the attribute is conforming behavior since such ODR-use doesn't
involve a call! I'm still content to drop the attribute as this PR does until
someone comes forth with good motivation for allowing `SYCL_EXTERNAL` to be
used with a variadic function and where all ODR-uses don't involve calls; such
use cases would be quite interesting! :)
