    go.bbclass: set TMPDIR during compilation
    
    The go build tool creates working directories under
    $TMPDIR for all of its processing.  Create a directory
    under ${WORKDIR} for this and point TMPDIR at it during
    compilation, so that systems that have a relatively
    small /tmp filesystems can still compile larger Go
    packages.
