Cannot build Qt w/ Wayland in Ubuntu 14.04.05

Qt 5.8.0 RC fails to compile w/ Ubuntu 14.04.05 + Wayland 1.10.0 when the QtWayland module is enabled. However, it successfully compiles if the QtWayland module is not enabled during configuration. This is a regression, as the Qt 5.8.0 Beta w/ QtWayland compiles successfully on the same setup.

Qt 5.8.0 RC was configured w/ the following args: ./configure -qt-xcb -opengl es2
The error message is as follows:
