coreboot intends to update our toolchain soon, and we'd like to get it thoroughly tested before we do, so we need everyone's help.
Please download the toolchain patch, build the new toolchain, then build and test any boards you're working on with it. You can either reply to this thread with your results, or email me directly.

Another option for testing the new toolchain is to use the docker coreboot-sdk image if you have a decent internet connection. This downloads about 1GB of docker containers which decompresses to about 3GB. From the coreboot directory, after setting up your config file, run:
% docker run -u root -it -v $PWD:/home/coreboot/coreboot --rm coreboot/coreboot-sdk:test /bin/bash -c "cd /home/coreboot/coreboot && make clean && make"
This leaves build files owned by root, so you'll need to chown them back: % sudo chown -R $(whoami):$(id -gn $(whoami)) .
Thanks for your help. Martin
