Thank you for the pointers but I tried to use the riscv64-xtoolchain-gcc
pkgs today and that fails neatly :

So today was a full day of trying with the instructions at the wiki
https://wiki.freebsd.org/riscv both with the toolchain built from
here https://github.com/freebsd-riscv/riscv-gnu-toolchain and then
again with the pkgs for FreeBSD 12. Fails.
So not sure how you or anyone is getting a bootable result but it
surely isn't documented anywhere.
I am baffled by what I see at
https://ci.freebsd.org/job/FreeBSD-head-riscv64-testvm/ as there can not
be any way to build FreeBSD for rv64imafdc unless someone has some pointers?
Has anyone anywhere actually done this? Recently ?
