x86: enable "make ARCH=x86"
After unification of the Kconfig files and
introducing K64BIT support in kconfig
it required only trivial changes to enable
"make ARCH=x86".
With this patch you can build for x86_64 in several ways:
1) make ARCH=x86_64
2) make ARCH=x86 K64BIT=y
3) make ARCH=x86 menuconfig
=> select 64-bit
Likewise for i386 with the addition that
i386 is default is you say ARCH=x86.
