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. SRCARCH is now set in the top-level Makefile because we need this info to include the correct arch Makefile.

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. make ARCH=i386 defconfig and make defconfig works as expected also after this change. But arch maintainers shall now update a defconfig file in the configs/ directory.

x86: do not use $(ARCH) when not needed For x86 ARCH may say i386 or x86_64 and soon x86. Rely on CONFIG_X64_32 to select between 32/64 or just hardcode the value as appropriate.

x86: correctly set UTS_MACHINE for "make ARCH=x86" For a kernel built with "make ARCH=x86" the following system information is displayed when running the new kernel $ uname -m x86 On some i386 systems (e.g. K7) we even have the following information $ uname -m x66 This is weird. The usual information for "uname -m" should be "x86_64" on 64-bit and "i386" or "i686" on 32-bit. This patch fixes the issue by setting UTS_MACHINE to "i386" for 32-bit kernel builds and to "x86_64" for 64-bit kernel builds. I.e., "x86" won't be used for UTS_MACHINE anymore.
