359e2e3525 depends: Add RISC-V support (Wladimir J. van der Laan)
Pull request description:
This adds support for riscv32 and riscv64 builds to the depends system.
The change consists of documentation and build system changes. The most significant change is an update of `config.sub` and `config.guess` inside zeromq patch, as the current version does not recognize the `riscv*` host tuples (there's no new version of ZeroMQ yet with newer ones).
Good thing: RISC-V 64-bit toolchain packages can be installed out of the box on Ubuntu 18.04+.
I would also like to add RISC-V 64-bit executables to gitian, but this will not be possible until #12511 .
