x86: unify arch/x86/kernel/Makefile(s)

Browse Source 
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.
