The script gen_gcc_docs.sh failed due to a timeout:
https://builder.sourceware.org/buildbot/#/builders/346/builds/366

It blames three commits, one of them is this one. I can't see
anything in any of the three commits that could have plausibly
caused it to timeout.

Please let me know if there's anything I can do.
