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.
