Subject: [PATCH 2/8] Makefile: Don't filter out -O2 from supplied flags for AVX2 builds
Date: Tue, 15 Nov 2022 02:23:43 +0100	[thread overview]
Message-ID: <20221115012349.2240096-3-sbrivio@redhat.com> (raw)
In-Reply-To: <20221115012349.2240096-1-sbrivio@redhat.com>

Drop it from the internal FLAGS variable, but honour -O2 if passed in
CFLAGS. In Debian packages, dpkg-buildflags uses it as hardening
flag, and we get a QA warning if we drop it:
  https://qa.debian.org/bls/bytag/W-dpkg-buildflags-missing.html
