Subject: [PATCH bpf-next 04/11] samples: bpf: use own EXTRA_CFLAGS for clang commands
Date: Tue, 10 Sep 2019 13:38:23 +0300
Message-ID: <20190910103830.20794-5-ivan.khoronzhuk@linaro.org> (raw)
In-Reply-To: <20190910103830.20794-1-ivan.khoronzhuk@linaro.org>

It can overlap with CFLAGS used for libraries built with gcc if
not now then in next patches. Correct it here for simplicity.
