+There was the same problem for lv2 with the autobuild system...
+lv2 uses waf too !
+
+It could correctly build on the Build System but failed with autobuild,
+for the same reason
+
+A workaround consists to modify the spec file :
+replace "./waf  %{?_smp_mflags}" with simply "./waf build"
+
+but it will take more time to build    :(
+
+
+A contrario :
+Ardour3 that uses waf can be built without any problem with the
+autobuild system :
+the spec file contains symply ; ./waf build
+
+
+Nevertheless, the autobuild system is now different from the
+BuildSystem, and I don't know if it's useful to modify your spec file,
+to be compliant with the autobuild, not knowing for now if the same
+modification will be applied inside the BS.
+
+NB some programs ask to use their own bundled version of waf... which
+means that modifying Mageia waf-rpm and the waf-python3.macros will not
+solve the problem of the smp_flags for them.
