[RFC - GIT pull] first step to get rid of x86_64 and i386 dirs

[Sam Ravnborg <sam@ravnborg.org>]

Hi Ingo.

This is first step in getting rid of the two directories.
I had to do some very minor modifications in common files
to let it work out - but nothing really hackish.

If you & Thomas + hpa are OK with the changes they can be
pulled from:

	git://git.kernel.org/pub/scm/linux/kernel/git/sam/x86.git

As this is mostly renames I have attached a git -M diff only.

The remaining stuff is Kconfig files.

Before looking into these I am hoping someone could
step in and make the two Kconfig.debug
files 100% equal - because then I can fix the kconfig
stuff and finally kill the two directories.

	Sam

    x86: move defconfig files for i386 and x86_64 to x86
    
    With some small changes to kconfig makefile we can now
    locate the defconfig files for i386 and x86_64 in
    the configs/ subdirectory under x86.

    x86: move i386 and x86_64 Makefiles to arch/x86
    
    Moving the ARCH specific MAkefiles for i386 and x86_64
    required a litle bit tweaking in the top-lvel Makefile.
    But this is one of the final steps to get rid of the
    x86_64 and i386 directories.
