During precise development, build-essential was accidentally marked Multi-Arch: foreign. This directly contradicts the multi-arch cross-building spec, and broke when dpkg started properly implementing that spec in quantal.

This bug has already been fixed in quantal, but the fix should be backported to precise for correctness (in case someone uses the quantal dpkg with the precise build-essential, or some other interesting combination).
