[dpdk-dev] [PATCH 1/2] config/arm: add non-SVE march for soc kunpeng930

[Chengwen Feng]

Currently, the soc_kunpeng930 declares '-march=armv8.2-a+crypto+sve',
but some compiler doesn't recognize the march because it doesn't
support sve.

This patch adds '-march=armv8.2-a+crypto' before
'-march=armv8.2-a+crypto+sve' so that:
1. If compiler doesn't support '-march=armv8.2-a+crypto+sve', then it
will fallback supports 'armv8.2-a+crypto'.
2. If compiler supports '-march=armv8.2-a+crypto+sve', then it will
compile SVE-related code.

Fixes: 7cf32a22b240 ("config/arm: add Hisilicon kunpeng")
