Actually, it was a bug, and only affects Alpine Linux 3.10.0. Any
3.10.x release newer than that will work just fine with the pre-existing
checks.
I don't really think it is necessary to have this check, as the
likelihood of anyone building GNU software by hand on Alpine Linux
3.10.0 at this point is low.
