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. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: "H.
