Subject: [PATCH 02/35] ifconfig: Improve the support for GNU/Hurd.

Use system specific code instead of generic code.
This provides abilities similar to other systems.

Subject: [PATCH 35/35] telnet: Several ioctls have been disabled in the Hurd's
 glibc

But not the related option macros. inetutils uses those macros to decide
whether the ioctls are available, so it is FTBFS now. The Hurd's glibc
is being fixed, but we'll use this for now to get the builds going.
