Doesn't:

obj-$(CONFIG_MODULES)		+= module_alloc.o
obj-$(CONFIG_KPROBES)		+= module_alloc.o

work just as well? The kbuild modules.rst documentation says:

        The order of files in $(obj-y) is significant.  Duplicates in
        the lists are allowed: the first instance will be linked into
        built-in.a and succeeding instances will be ignored.

so you should be fine... or the documentation is wrong!
