Yes, you can satisfy this dependency...

depends on BR2_PACKAGE_GLMARK2_GL || BR2_PACKAGE_GLMARK2_EGL_GLES

...and be able to select the glmark2 package from the menu despite of 
not satisfying the BR2_PACKAGE_HAS_UDEV dependency. In fact, you will 
still see the comment on the menu, but the comment about the opengl 
stuff will be replaced by the package so you can select it.

Vincent.
