Makefiles no longer need to include Rules.make, which is currently an
empty file.  This patch removes it from the arch tree Makefiles.

Second try ready.
Other architectures does not practice this, but I added a rule to
copy vmlinux.gz + bootloader to root of kernel-tree.

bootloader is build when needed, therefore the boot: target has not been
re-introduced.

Complete summary of changes:
o Copy vmlinux-gz + bootloader to root of kernel-tree
o Fix make

	code-duplication that existed between ACPI and the ia64 IOSAPIC code.
	To make this work, the Makefiles had to be re-organized to ensure that
	the ACPI subsystem is initialized before PCI (even though both are called
	via subsys-initcalls).
