From: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>

Follow the changes in Clang search paths and specify sysroot via the
TOOLCHAIN_OPTIONS, otherwise clang will fail to find system headers when
executed by bindgen.

For SDK packages TOOLCHAIN_OPTIONS don't contain full sysroot path, so
specify the correct directory explicitly.
