People may want to build TensorFlow with a local toolchain that has no download URL. This pull request enables such scenarios by skipping the toolchain download when $CROSSTOOL_URL is empty.
In addition, this pull request enables scenarios where one works with a toolchain that is structured so that a /usr/include hierarchy for the headers is inside some other directory (configurable as $CROSSTOOL_ROOT) - not inside the absolute path /usr/include. If $CROSSTOOL_ROOT is left empty/unconfigured by a configuration, everything shall work as it did before this pull request.
