    archiver: preserve sysroot paths in configured mode
...

In meta/conf/multilib.conf, it overrides the variables
of STAGING_DIR_HOST, STAGING_DIR_TARGET and RECIPE_SYSROOT
with "${WORKDIR}/${MLPREFIX}recipe-sysroot".

So the archiver should also expand STAGING_DIR_HOST and
STAGING_DIR_TARGET to preserve sysroot paths in configured mode for
multilib.
