    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.
