    x86: unify arch/x86/kernel/Makefile(s)
    
    Combine the 32 and 64 bit specific Makefiles in one file.
    While doing so link order was (almost) preserved on 32 bit
    but on 64 bit link order changed a lot.
    
    Patch was checked with defconfig + allyesconfig builds.
    The same .o files were linked in these configurations.
    
    To keep readability of the Makefiles a few Kconfig
    symbols was added/modified and it was checked that
    they were not used anywhere else.
