acl: fix compiler flags with meson and AVX2 runtime
When compiling the ACL library on a system without AVX2 support, the flags used to compile the AVX2-specific code for later run-time use were not based on the regular cflags for the rest of the library. This can cause errors due to symbols being missed/undefined due to incorrect flags. For example, when testing compilation on Alpine linux, we got: error: unknown type name 'cpu_set_t' due to _GNU_SOURCE not being defined in the cflags. This issue can be fixed by appending "-mavx2" to the cflags rather than replacing them with it. Fixes: 5b9656b157d3 ("lib: build with meson") Cc: stable@dpdk.org Signed-off-by: Andrius Sirvys <andrius.sirvys@intel.com> Acked-by: Bruce Richardson <bruce.richardson@intel.com>
