I compile the image and SDK for board using Yocto. Compiling the image(without -c populate_sdk) looks ok, but when I try to populate an SDK I get a couple of errors (seems the issue is in "meta-qt5" layer).
So, I use bitbake <image_name> -c populate_sdk. The branch is rocko. After executing bitbake i get the next errors:
ERROR: qt3d-5.9.8+gitAUTOINC+0d923f9fc3-r0 do_compile: Function failed: do_compile (log file is located at /opt/PHYTEC_BSPs/IMX6/build/tmp/work/cortexa9hf-neon-phytec-linux-gnueabi/qt3d/5.9.8+gitAUTOINC+0d923f9fc3-r0/temp/log.do_compile.2150)

Here are the log files: qt_webkit and qt3d. They are quite large but can be useful.
Also, I compile it on Ubuntu 16.04 Virtual machine (4 CPU, 8GB RAM)
Found a solution for Ubuntu 18.04.
For building SDK It's necessary to install some additional software. Try to exec the next commands and re-run the bitbake.
sudo apt-get update
sudo apt-get install -y -q --no-install-recommends -o Dpkg::Options::="--force-confdef" \
-o Dpkg::Options::="--force-confold" build-essential chrpath cpio diffstat file \
g++-multilib gawk gcc-multilib git-core locales openssh-client python python3 \
socat sudo texinfo tmux unzip wget
sudo rm -rf /var/lib/apt/lists/*
sudo locale-gen en_US.UTF-8
export LANG='en_US.UTF-8' LANGUAGE='en_US:en' LC_ALL='en_US.UTF-8'
I am not sure about Ubuntu 16.04, but on 18.04 everything works fine for me.
