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!
