> Subject: [XEN PATCH v9 06/30] build: rework test/livepatch/Makefile
>
> This rework the livepatch/Makefile to make it less repetitive and make
> use of the facilities. All the targets to be built are now listed in
> $(extra-y) which will allow Rules.mk to build them without the need of
> a local target in a future patch.
>
> There are some changes/fixes in this patch:
> - when "xen-syms" is used for a target, it is added to the dependency
> list of the target, which allow to rebuild the target when xen-syms
> changes. But if "xen-syms" is missing, make simply fails.
> - modinfo.o wasn't removing it's $@.bin file like the other targets,
> this is now done.
> - The command to build *.livepatch targets as been fixed to use
> $(XEN_LDFLAGS) rather than just $(LDFLAGS) which is a fallout from
> 2740d96efdd3 ("xen/build: have the root Makefile generates the
> CFLAGS")
>
> make will findout the dependencies of the *.livepatch files and thus
> what to built by "looking" at the objects listed in the *-objs
> variables. The actual dependencies is generated by the new
> "multi-depend" macro.
>
> "$(targets)" needs to be updated with the objects listed in the
> different *-objs variables to allow make to load the .*.cmd dependency
> files.
>
> This patch copies the macro "multi_depend" from Linux 5.12, and rename
> it to "multi-depend".
