Compiling xmrig-amd on Armv8, during make SSE2NEON.h throws erros
I've been trying to compile xmrig-amd on a Rock Pi 4 as a test bed for being able to get OpenCL GPU mining to other platform.  Some of the chips that now support Open CL are the allwinner H6, RK3399/Pro, AML-S912, S922/X, A311D.  I've so far been able to get sgminer running and mining with opencl.  

The issue that I am having with xmrig-amd starts after 87%, The error is related to the SSE2NEON.h file and calls to stdinth.  The images below give more detail on what is happening  during the compilation and build process
