Maix Go / K210 stuff

First, get the Kendryte C toolchain and copy or symlink the contents of the src/ folder to a checkout of https://github.com/sipeed/LicheeDan_K210_examples.git.

Then to build a certain project do:

mkdir build && cd build
cmake .. -DPROJ=<ProjectName> -DTOOLCHAIN=/opt/riscv-toolchain/bin && make

You will get 2 files, build/<ProjectName> and build/<ProjectName>.bin. The former is an ELF executable, the latter a raw binary that can be flashed or written to 0x80000000 in SRAM and directly executed.
