[Buildroot] Error when building Qt5 Webengine from buildroot

Hey Thomas,

> Which version of gcc are you using? Does it support C++11 ?

The gcc version is 5.4.0, and when I pass the -std=c++11 it will build for c++11.  Here is the gcc version:

$ buildroot/output/host/usr/bin/arm-buildroot-linux-gnueabihf-gcc -v
Using built-in specs.
