armv8-a has optional CRC32 extension, march=armv8-a+crc enables code generation for the ARMv8-A architecture together with the optional CRC32 extensions. added RTE_MACHINE_CPUFLAG_CRC32 to detect the availability of CRC32 extension in compile time. At run-time, The RTE_CPUFLAG_CRC32 can be used to find the availability. armv8-a+crc target support added in GCC 4.9, Used inline assembly and emulated __ARM_FEATURE_CRC32 to work with tool-chain < 4.9 Signed-off-by: Jerin Jacob <jerin.jacob@caviumnetworks.com>
