Compile does not work for xm510

[schneemaier]

After a succesful build for xm530 i tried to build the system for xm510. I did not change any setting and on the first try i ended up with the following error

This was an easy fix with copying compiler-gcc7.h from openipc-2.1/br-ext-chip-hisilicon/board/hi3516cv300/kernel/overlay to br-ext-chip-xiongmai/board/xm510/kernel/overlay/include/linux

After this the compile fails wtih the following error:

I am not sure where the tools/env/fw_env.c file is which needs some patching
