+Mageia will have to wait for sometime :...
+There are 21 makefiles
+There are 0 or 1 or 2 links to add to them (but which of them really
+need the added links ?)
+Than means some combinations to try :
+2 square to the power of 21 = 2097152 if I blindly test all of them !
+If I win early I will try the casino
+;-)
+
+I will try a rational approach to decrease the number of tests to do...
+
+Anyway... Did you think that inactivating the --as needed option will
+imply  so much time to build only one package ?
+
+I really am afraid with this !
