Packages which inherit fontcache.bbclass call postinstall script
update_font_cache. And in update_font_cache, it calls ${bindir}/fc-cache
by qemuwrapper. When multilib is enabled, both packages foo and lib32-foo
will call ${bindir}/fc-cache and one of them will fail to run obviously.
Duplicate install file fc-cache to ${libexecdir} with ${MLPREFIX} and
call proper fc-cache in update_font_cache.
