No, not if you are cross compiling since ARCH=x86 isn't specific to
either, we would have to look at the config. In that case it is better
to do something like:
x86|i386|x86_64)
debarch=$(grep -q CONFIG_64BIT=y .config &&
echo amd64 || echo i386) ;;

I only included the major Debian architectures in my patch since, I
don't know enough about all the smaller architectures and there config
dependencies. I have however added mips as it seemed straight forward.
AFAICT there are some problems surrounding sparc, since sparc in debian
uses 64-bit kernels, 32-bit userland, and the new sparc64 port uses
64-kernels and 64-bit userland, so we have no way of knowing if the
64-bit sparc kernel should have the Architecture field set to sparc or
sparc64.
For now I will just set it to sparc, as that is a release candidate for
squeeze, where sparc64 isn't nearly that far along.
sparc*)
debarch=sparc ;;
mips)
debarch=mips$(grep -q CPU_LITTLE_ENDIAN && echo el) ;;
I will sum these up in a new revision of the patch, when I get an ack
from Michal or a Debian kernel team member.
