The Xen build system is not currently compatible with the --as-needed linker option. The proper fix for this is turning out to be rather invasive to the build system so simply disable for now with the intention of revisiting for the 4.2 release. The --no-as-needed option is available at least since binutils 2.15 (released in May 2004) and hence I think can be unconditionally relied on.
