I only noticed on buildd.d.o that the failure was the same there.

If you're not convinced, then the patch you have is fine. It would fix
the immediate FTBFS on kfreebsd-* and this could be revisited later.
I was only trying to kill two (or more) birds with one stone here, by
accommodating GNU/Hurd, and keeping portability to some other future
k*BSD port, and if the patch is forwarded upstream they might like it to
fix this on other arches they support.

I'm not sure... be warned that packages.d.o might not be indexing
package contents for GNU/Hurd. (At least once before this has caught me
For the Hurd, I thought, if the header inclusion test was AF_LINK:
1. if it supports sockaddr_dl, and has net/if_dl.h, it would be fixed
2. if it supports sockaddr_dl, but currently lacks net/if_dl.h, the new
build error would make the problem clearer, and it could build in future
without changes after they provide the missing net/if_dl.h
3. if it doesn't support sockaddr_dl, the AF_LINK test is wrong in
_both_ places so it wouldn't be able to build anyway; we'd be no worse-off.

I was assuming that platforms without sockaddr_dl don't define AF_LINK.
I don't see it in the Linux headers.
And the FXR pages also showed a correlation between AF_LINK being
defined on a platform, and the existence of a net/if_dl.h containing the
definition of sockaddr_dl.
