From 5aef3880c6dcb4d488aec277dad4e620e1fe9436 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Tue, 29 May 2018 10:26:06 +0200 Subject: 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.
