Describe the bug

bsp/cvitek/cv18xx_risc-v/SConstruct 中以下赋值操作看上去是没有用的，反而容易引起混淆

rtconfig.CPU='virt64'
rtconfig.ARCH='risc-v'

bsp/cvitek/cv18xx_risc-v/rtconfig.py 中已经设置了 ARCH 和 CPU 如下：

ARCH        ='risc-v'
VENDOR      ='t-head'
CPU         ='c906'
CROSS_TOOL  ='gcc'

估计是从virt那边复制过来的

我猜是，后面我找个时间提个 PR 给它删掉
