Subject:     cmd: Use correct install tool dir with gccgo
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f0e064fb9a99259eb91d6e355deca7dc16ca3c85;p=thirdparty%2Fgcc.git

cmd: Use correct install tool dir with gccgo

    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.
