[Xen-devel] [XEN PATCH v3 17/23] xen/build: Start using if_changed

2020-02-26 Thread Anthony PERARD
This patch start to use if_changed introduced in a previous commit. Whenever if_changed is called, the target must have FORCE as dependency so that if_changed can check if the command line to be run as changed, so the macro $(real-prereqs) must be use to discover the dependencies without "FORCE".
