+- Change from simple %defines to %bcond_with/without, as this
+  allows to be set in prjconf without the need to patch the .spec
+  files.
+  + build_wayland has been replaced with the equivalent
+    %bcond_with, resp. %bcond_without, based on the value that was
+    originally set, resuting in no change for the build.
