configure.in checks for "ARMv8 CRC32C intrinsics" and goes as far as adding "-march=armv8-a+crc" to the target flags if the compiler allows it. This can clash with the OpenWrt target flags in CONFIG_TARGET_OPTIMIZATION. If for example the latter is set to "-mcpu=cortex-a9" the following warning is issued: cc1: warning: switch '-mcpu=cortex-a9' conflicts with '-march=armv5t' switch This commit prevents configure.in from adding the mentioned flag. The addition is unwanted when cross-compiling. An issue was raised for this recently, see [1].
