If the kit includes a correctly configured sysroot gdbserver will tell us our hostPath. Respect that hostPath if it exists, otherwise fall back to remote debug. Also, populate the hostPath with the symbol file from the run parameters. Task-number: QTCREATORBUG-29614 Change-Id: I3838cd44aa96d7dfcd4ded660b8102a1532c5362 Reviewed-by: hjk <hjk@qt.io>
