Here is a proposal to rewrite the option names and prompts:

    choice
        bool "OpenGL support"
        default BR2_PACKAGE_LIBEFL_X_XLIB_OPENGL   if BR2_PACKAGE_HAS_LIBGL
        default BR2_PACKAGE_LIBEFL_X_XLIB_OPENGLES if BR2_PACKAGE_HAS_LIBGLES
        help
          libevas can be configured to use HW acceleration with OpenGL
          or OpenGLES.

    config BR2_PACKAGE_LIBEFL_X_XLIB_OPENGL_NONE
        bool "none"

    config BR2_PACKAGE_LIBEFL_X_XLIB_OPENGL
        bool "opengl"
        depends on BR2_PACKAGE_HAS_LIBGL

    comment "opengl support needs an OpenGL provider"
        depends on !BR2_PACKAGE_HAS_LIBGL

    config BR2_PACKAGE_LIBEFL_X_XLIB_OPENGLES
        bool "opengles"
        depends on BR2_PACKAGE_HAS_LIBGLES

    comment "opengles support needs an opengles provider"
        depends on !BR2_PACKAGE_HAS_LIBGLES

    endchoice

If you fell inclined into adoptiong this, update the corresponding
options in the .mk, of course.

Regards,
Yann E. MORIN.
