+Subject: [PATCH] Handle absolute sysconfdir when installing symlinks
+
+sysconfdir defaults to /etc when the prefix is set to /usr. But joining
+MESON_INSTALL_DESTDIR_PREFIX and sysconfdir when the latter is an
+absoulte path, results in sysconfdir only. Which might lead to an error
+during install because /etc/fonts/conf.d/ might already exist from an
+pre-existing fontconfig installation.
