It's not necessary. I recreated the failing build locally.

The only difference I could find was that the CI image uses pdftex to
build out-www/cs/notation.pdf, while the passing build (locally on my
laptop) uses xetex. The build also passes in a ubuntu 16.04 container
with xetex installed.

here is the diff:

It's "working" with origin/master today because cs/GNUmakefile
disables PDF generation, I don't know why.

You can run it locally. There is a significant speedup for parallel builds.

Another things to consider (if you build docs locally) if to remove
extractpdfmark. It is extremely slow.
