iasl is been check for presence by ./configure, so this Makefile doesn't have to do it. Also start to use $(IASL) that ./configure generate. iasl hasn't been download by our build system for a while and the dependency on iasl is in the main xen.git README. Make use of $< in one rule instead of spelling the %.asl file again. Signed-off-by: Anthony PERARD <anthony.perard@citrix.com> Acked-by: Andrew Cooper <andrew.cooper3@citrix.com>
