Actually thinking about it some more I'd be happier arguing for a freeze
exception for something like the below which only handles the actual
valid values of XEN_TARGET_ARCH and not the GNU names (which cannot
happen) and prints an error for unknown architectures (so new ports
aren't bitten in the future, etc).

Konrad, wrt the freeze I think this is low risk for breaking x86
platforms and makes things work for arm, so is worth it.

Subject: [PATCH] mkdeb: correctly map package architectures for x86 and ARM

mkdeb previously set the package architecture to be 'amd64' for anything other than
XEN_TARGET_ARCH=x86_32.  This patch attempts to correctly map the architecture
from XEN_TARGET_ARCH to the Debian architecture names for x86 and ARM
architectures.

v3 (ijc): Handle only valid values for $XEN_TARGET_ARCH, print an error if the
arch is unknown.
