This change fixes extraction of the unprocessed args and also implements
few minor changes that @eerhardt has asked for, like renaming the new argument
and changing usage of HostRid to Rid in build/BuildDefaults.props.
This change enables RHEL 6 support. It also adds a new command line option to the
run-build.sh script that enables passing in a folder containing a bootstrap CLI.
This helps in bringup of new target platforms.
