ConfigureBuildQt: Do another round of configure

After all repos are configured and built, do another round of
reconfigure.

This can catch issues in the find_package of plugins. E.g. when running
the builds for qtbase -> qtdeclarative -> qtmultimedia, during the
first pass qtdeclarative is reconfigured without any plugins present,
but in the second pass additional plugins will be added in the
`find_package` chain.
