[Bastien Nocera <hadess src gnome org>]

commit ceb066a1ea088f63597a39f0188d2bac7301171e
Author: Iñigo Martínez <inigomartinez gmail com>

    build: Remove unused defines
    
    meson generates the config.h file with multiple defines to be used
    as compile-time options, in the same way as autotools does. However,
    some of them are not used.
    
    This patch removes those unused defines.
