    go-1.8: add patch for set soname in ELF shared objects
    
    The go link tool does not set the soname by default, which
    prevents package.bbclass's shlibs processing from seeing
    shared libraries built with go.
    
    This patch passes appropriate options to go's linker and
    the external linker to set the soname.
