    Subjectkbuild: Separate ouput directory support
    The following set of patches introduce support for
    separate output directory when building a kernel.
    Typical usage is building several kernels with different configurations -
    but based on the same kernel src.

    Consider the following setup:
    /home/sam/bk/linux-2.6 <= kernel src

    /home/sam/kernel/mars <= My workstation
    /home/sam/kernel/defconfig <= defconfig for compiletime testing

    Then in order to handle the two different configurations I just have to do:
    cd /home/sam/bk/linux-2.6
    make O=../../kernel/mars

    And the same for the defconfig version.

    All output files are stored in the output directory, including .config.
    [Thanks to Roman Zippel which made this loong time ago in kconfig].

    The patch has been in existence in several months but only lately becoming
    in a suitable state ready for inclusion. It is developed based on an initial
    concept made by Kai Germaschewski, but refined a lot since then.
    It works with a kernel based on default configuration (make defconfig).

    It is divided up in the following parts:
    core the kbuild changes to support separate output directory
    ieee Fix in ieee Makefile
    i386 Fix in i386 Makefiles + new syntax enabled for always
    This was required because i386 had an executable located in
    a subdirectory.
    include Fixes for errornous include paths, and one place where a generated
    .c file references a .h file in the kernel tree.
