[Iñigo Martínez <inigomartinez src gnome org>]

commit c663fb93985fd68f03dea62f5951742c3ac719ed
Author: Iñigo Martínez <inigomartinez gmail com>

    build: Remove unused defines
    
    meson generates the config.h file with multiple defines to be used
    as guards, in the same way as autotools does. However, almost all of
    them are not used.
    
    This patch removes the unused defines.
