Hey ! You ! you are a happiness breaker  :-(

Argh !
You killed me ;-(

You gave me some more work indeed :

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 !
