kbuild: add generic mergeconfig target, %.config
"scripts/kconfig/merge_config.sh && make oldconfig" works well enough for merging local config fragments, but Kbuild currently has the entry points only for "kvmconfig" and "tinyconfig". This commit provides the generic target for mergeconfig, so we can manage our own config fragments easily: put "foo.config" in arch/$(SRCARCH)/configs/ or kernel/configs/, and then run "make foo.config". Now "make kvmconfig" is just a shorthand of "make kvm_guest.config". Likewise, "make tinyconfig" is equivalent to "make allnoconfig tiny.config".
