kbuild: disable modpost warnings for linkonce sections

Disable modpost warnings for linkonce sections My build gives lots of warnings like WARNING: sound/core/snd.o (.gnu.linkonce.wi.mpspec_def.h.30779716): unexpected section name. The (.[number]+) following section name are ld generated and not expected. Did you forget to use "ax"/"aw" in a .S file? Note that for example <linux/init.h> contains section definitions for use in .S files. But for .linkonce. duplicated sections are actually ok and expected. So just disable the warning for this case.
