That's the full error log, from the linker, I believe.  It's the xtfpga
config for the xtensa architecture.  It's one of the few that buildman
won't fetch a good toolchain for so you'll want to look at
tools/docker/Dockerfile and see we get it from
https://github.com/foss-xtensa/toolchain/releases/download/2020.07/x86_64-2020.07-xtensa-dc233c-elf.tar.gz
if you don't have the CI builder container itself handy already.
