For cases where the compilation microarchitecture is explicitly given, we extract the cpu-flags to use from the compiler rather than hard-coding. This means that we will only ever use instruction sets supported by the compiler, rather than having a case where the uarch and the Intel DPDK both support a given instruction-set, but the compiler does not. In the case where 'native' uarch support is requested, the same mechanism is also used to detect the instruction-sets supported Signed-off-by: Bruce Richardson <bruce.richardson@intel.com> Signed-off-by: David Marchand <david.marchand@6wind.com>
