configure: override AR_FLAGS to silence warning
The automake default ar flags are 'cru', but the 'u' flag in there
causes warnings on many modern Linux distros. Removing 'u' may have a
minor performance impact on older distros but should not cause harm.
Explained on the automake mailing list already back in April 2015:

Reported-by: elephoenix on github
Fixes #2617
Closes #2619
