Closes #114

Besides other issues, this should fix an integer overflow breaking IPv6 address
aquisition after a runtime of 50 days.

This also removes our mac80211 backport for now, as the version found in
Attitude Adjustment is up-to-date.

This fixes targets like toolchain/clean.

They can still be enabled by supplying BROKEN=1.
