Ping: [XEN PATCH v9 04/30] build: set ALL_OBJS in main Makefile; move prelink.o to main Makefile

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Hi Julien, Stefano,

This patch has some changes to the Arm makefiles. Could you have a quick
look or ack the changes?

They are some other patches in the series which might want a Arm ack:
- 20/30 build: rework "clean" to clean from the root dir
- 24/30 build: grab common EFI source files in arch specific dir
- 25/30 build: replace $(BASEDIR) by $(objtree)

Cheers.
