    Subject[PATCH] kbuild, deb-pkg: fix Architecture field when cross compiling
    Date
    If the environment variable CROSS_COMPILE is set, override
    the Architecture control field, based on the value of the
    ARCH environment variable.

    With this patch the following make command:

    make CROSS_COMPILE='' ARCH=i386 deb-pkg

    will output an i386 Debian package instead of an amd64 one,
    when run on amd64 machine.
