+Subject: [PATCH qtbase] eglconvenience: add egl to CONFIG to get correct include
+ paths
+
+The eglconvenience code includes <EGL/egl.h>. Therefore, it should get
+the appropriate EGL-specific include paths from QMAKE_INCDIR_EGL,
+otherwise the build might if the EGL library has its headers in
+special locations. In order to achieve this, we simply add the "egl"
+feature to the list of features imported by eglconvenience.
