Hi,

this adds OpenOCD with RISC-V support to Guix.

There is a problem though: riscv-openocd bundles libjaylink, which is
also available as a package. The available package cannot be used
because it is too old and riscv-openocd has riscv-specific additions
made to it. So the question is: does this justify using the bundled
library or should I do something? (if yes, what?)

I have successfully used the package to communicate via JTAG with a
Sipeed Nano and a JLink V8.

I built this package successfully on: x86_64-linux, aarch64-linux
