The gcc version in CentOS 7 is 4.8.2 (released in Mar 2013). But Arm added the support for 'arm_acle.h' in gcc 5.1 (released in Jun 2014). And there are also some bugs in Arm gcc 4.8. The patch is to detect GCC(greater than 5.1) version for Arm crc32c. Change-Id: I718b9b89f952fed72c8795a176ebbe5395c8dd5e Signed-off-by: Yuqi Gu <yuqi.gu@arm.com>
