    net: don't run multicast listen test on nil interface in short mode
    
    This is a backport of https://golang.org/cl/17154.
    
    The gccgo bug report https://gcc.gnu.org/PR65785 points out that the
    multicast listen tests will use the network even with -test.short.
    Fix test by checking testing.Short with a nil interface.

    When using the go command built from gccgo to build and
    install a go tool, use the value from runtime GCCGOTOOLDIR as
    the install directory.
    
    This also fixes the output from 'go tool' when used with the
    gccgo-built go command, to only include the go tools and not
    other binaries found in the same directory.
