xen, xen-tools: remove stubs task and use multilib when necessary

The stubs task was MACHINE-specific due to the OE variables it accessed
which had forced unnecessary rebuild work in OpenXT's multi-MACHINE
builds.

The stubs task was generating a 32-bit header file to satisfy the Xen
tools firmware build to generate the hvmloader binary, which is only
needed on x86-64 targets where HVM-mode guests are enabled.

Remove this header file generation logic and similar in the configure
task, and in the cases where hvmloader is to be built use multilib to
provide a 32-bit sysroot and allow the build to obtain the needed 32-bit
materials from their source: glibc.

Building Xen tools for x86-64 with HVM-guest support enabled now
requires the following to be added to a build conf file
(eg. distro.conf, or local.conf) :

    require conf/multilib.conf
    MULTILIBS = "multilib:lib32"
    DEFAULTTUNE_virtclass-multilib-lib32 = "x86"
