Kernel header packages should be labelled with the target architecture.
This is because the headers include some generated files that are both
architecture- and configuration-specific.

Any package of libraries or headers for some architecture is in theory
useful for cross-development on any other architecture, yet we do not
label them as architecture: all.  If we did that, we would then have to
use a different name and installation path for each target so that they
are co-installable; this would also bloat the package list files.  You
should normally be able to convert a package for use in cross-
development using dpkg-cross, which changes its name and paths
accordingly.  However I don't know how well this will work for kernel
headers.
