[yocto] [Yocto][meta-qt5][qtwayland]Qtwayland recipe fails with Yocto 2.5

[Priyanshu Sharma]

Found that the missing features.egl is provided by QTBase recipe. And in my
case, qtbase is not compiling the feature "EGL" and thats why qtwayland
fails to find it.

egl is not included in PACKAGECONFIG of qtbase recipe. However, it used to
be enabled with Yocto 2.2.
Adding it PACKAGECONFIG[eg] of qtbase is not enabling it. How can egl be
enabled in qtbase?

Warm regards,
Priyanshu Sharma
