Cannot build using riscv gcc on Debian
Hello, I tried to build some examples for a RISC-V architecture on a Debian machine having installed the requirements specified in this repo's description, but ran into a error. However, using a RISC-V compiler from SiFive's GNU Embedded Toolchain — v2020.12.8 works.

Has anybody experienced this issue before?
8.3.0.2019.08+dfsg-1 that 2019 is conspicuously old.
I don't believe we have anyone who uses Debian as their primary distribution, so I don't think we have a sense of which packages are necessary on Debian-proper. If you have a path to a working toolchain / install directions for Debian, I imagine we would appreciate a PR updating the README with directions for Debian. @bradjc might have a better sense of the risc-v packaging.
I still live in a pretty ARM-only universe. All I do is keep building RISC-V off by default, because their toolchain installation is sadly still a mess (which, this unfortunately just continues to serve as evidence of :/ ).
You are missing a libc, which libtock-c expects.
You can build it yourself, which the README describes, just look for the section If you would rather compile your own newlib-based libc, follow the steps below.
For Debian you should also be able to use picolibc though. You should be able to just install the package https://packages.debian.org/stable/devel/picolibc-riscv64-unknown-elf which includes support for 32-bit RISC-V
I had a go at updating the documentation to include instructions using Debian. Try following this and let me know how it goes: https://github.com/alistair23/libtock-c/tree/alistair/rv32-support
I've tried the following with no success:
~/libtock-c/examples/c_hello$ git checkout alistair/rv32-support
Branch 'alistair/rv32-support' set up to track remote branch 'alistair/rv32-support' from 'origin'.
Switched to a new branch 'alistair/rv32-support'

As I've already mentioned, yes.

For debugging it's useful to see the command being run, that can be enabled with V=1.
Also, the README in that branch is apparently wrong, you need to use PICOLIBC=1 (I have updated the README)
So the entire command should be:
make PICOLIBC=1 V=1
Using your branch and PICOLIBC works.
$ make PICOLIBC=1
