Bug#959984: krb5: Add "Multi-Arch: foreign" to krb5-doc

[Sam Hartman]

Ah!
Never mind.
You opened a merge requests *months ago* and now are getting around to
opening a BTS bug because I'm a bad maintainer and didn't respond to
your merge request.
Got it.
Apologies.
I'll get to this in a couple of days.
I think I was busy being a less-bad DPL back then:-)
