Subject: [PATCH RFC bpf-next 04/10] samples: bpf: use own EXTRA_CFLAGS for clang commands
Date: Fri, 30 Aug 2019 03:50:31 +0300	[thread overview]
Message-ID: <20190830005037.24004-5-ivan.khoronzhuk@linaro.org> (raw)
In-Reply-To: <20190830005037.24004-1-ivan.khoronzhuk@linaro.org>

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