Installing / using gcc6 is the option for now.
--> Upstream bug.

I did not fix the issue but used a work around that I did publish in the mailing list.
Here is a copy of the mail.

either we are compiling native tools with unrequired switches and then it's a bug, either we have a "silent" direct requirement for a given compiler release and then it's a bug as well. In the mean time, I went around the issue by forcing the use of gcc6 by default on my pc. After installing gcc6 and g++-6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 20
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 10
sudo update-alternatives --set gcc /usr/bin/gcc-6 # g++
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 10
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-6 20
sudo update-alternatives --set g++ /usr/bin/g++-6

When the host is Ubuntu 14.04, qtwebengine build will fail. This problem is because the build of qtwebengine does not use native-gcc, but uses host-gcc.
*The gcc version of Ubuntu 14.04 is 4.8.x.
