Yes I can reproduce these issues. I think this is because that
the new version of libftd2xx is based on libusb-1.0 and that
libusb-1.0 needs libpthread and librt.
Supposedly dynamically
link to libusb-1.0 will not need these two.

Nothing wrong. I can reproduce your issues as well. I think the latest
d2xx library needs some fix from the OpenOCD side or from the d2xx side.
