support for making linux-libc-dev coinstallable under multiarch

[Steve Langasek]

Hello,

This is the patch from bug #750585 on the linux package, which I've just
gotten a freeze exception for; I've been told to send it to the mailing list
for sign off.  Please include this in the linux package for natty.

Thanks,
