Greetings,

Compile breaks when using the following command:
    fakeroot make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- deb-pkg

With 'set -x' in scripts/package/builddeb, the relevant output is:
    + '[' -n '' ']'
    ++ dpkg --print-architecture
    + arch=i386
This indicates that KBUILD_DEBARCH is not set.

The debian/control file is written with the following section:
    Package: linux-headers-2.6.39-rc5+
    Provides: linux-headers, linux-headers-2.6
    Architecture: i386
    Description: Linux kernel headers for 2.6.39-rc5+ on i386
     This package provides kernel header files for 2.6.39-rc5+ on i386

This produces the following error output:
    + forcearch=-DArchitecture=armel
    + dpkg-gencontrol -isp -DArchitecture=armel
-plinux-headers-2.6.39-rc5+ -P/opt/kernel-linus/linux-2.6/debian/hdrtmp
    dpkg-gencontrol: error: current host architecture 'armel' does not
appear in package's architecture list (i386)

Regards,
Robert
