    devel/libtool: pass through -fuse-ld flags
    
    GCC and Clang support a -fuse-ld flag to select between bfd, gold, and
    lld. As we migrate to lld as the base system linker we need to use this
    to fall back to bfd for ports that rely on its permissive behaviour.
    
    An equivalent change has been committed to libtool upstream in Feb 2016,
    but has not yet made it into a release.
