    Fix libgloss being built for disabled multilibs
    
    Target libraries are considered to be built for GCC's "host", not GCC's
    "target".  The "host" variable must be set by configure scripts using
    "config-ml.in" to determine multilib support, otherwise disabled
    multilibs (specified as a configure argument with --disable-<multilib>)
    will still be built for the subdirectories those configure scripts
    reside in.
