[Xen-devel] [XEN PATCH v2 07/12] xen/build: run targets csopes, tags, .. without Rules.mk

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Those targets make use of $(all_sources) which depends on TARGET_ARCH,
so we just need to set TARGET_ARCH earlier and once.

XEN_TARGET_ARCH isn't expected to change during the build, so
TARGET_SUBARCH and TARGET_ARCH aren't going to change either. Set them
once and for all in the Xen root Makefile. This allow to run more
targets without Rules.mk.
