[Xen-devel] [PATCH] ia64: consolidate final linking step

["Jan Beulich" <JBeulich@xxxxxxxxxx>]

This basically makes the final linking stage identical to x86's (with
the sole difference being that ia64 has the linker generate a map file,
while x86 doesn't), so would generally allow moving the final linking
rule into xen/Rules.mk.
