Building awscrt for RISC V

Hi all,

just trying to use AWS IoT Core on my Mango Pi board (riscv64 architecture). To do so, I need awscrt, among others. There is no precompiled binary for this architecture and the build fails with

~/crt/aws-lc/generated-src/linux-riscv64/crypto: No such file or directory

So I wonder whether someone tried this platform before and may share some thoughts/ideas.

Thanks, Jaroslav

full listing follows, just in case I am doing something stupid:

pi@nezha:~$ python3 -m pip install awscrt
