The first line is the correct one. The second line was the one
originally introduced, but it was a bug. The idea here is that if
LIBGLES has no dependencies, then it means that no OpenGL
implementation was selected.

This happens when no package provides a libEGL implementation, i.e
LIBEGL_DEPENDENCIES is empty.
