kbuild: -DMODULE for assembler source

For consistency, it makes a lot of sense to add -DMODULE (plus
the other special switches with CONFIG_MODVERSIONS) to .S files
which get assembled. It surely fixes an ugly workaround for
sparc64, guess we'll see if it breaks something for other archs
(I wouldn't think so, though)
