Hi, Guenter:

This built failure is because the toolchain version you used is not
supported the latest intrinsic function/macro.
We are sending the latest patchset now and we expect the whole new
features will be supported in gcc8.0.0 and binutil2.31+.

If you'd like to get these new features of toolchain, you may use the
github version.
This is the built-script repo. https://github.com/andestech/build_script.git
