Such a test will have to wait. Filtering to prevent symbols from being emitted
is not yet in place and there are a few existing tests that are dependent on
such symbols being emitted during device compilation; presumably
unintentionally. One of the next two PRs will add such filtering and remove/fix
such tests. Additionally, an attribute to support `SYCL_EXTERNAL` does not yet
exist upstream, so there is no syntax that can currently be used to write such
a test.
