vendor/qcom/proprietary/prebuilt contains binaries for
qcom/proprietary modules whose sources will not be shipped out
to some customers. The prebuilt folder will be populated as
a part of the automation process as per
release/ship_out_<target>_<variant>. This script is invoked
during source/envsetup.sh. It copies binaries from vendor/qcom/
proprietary/prebuilt to croot/out.
