There are some outdated measurements of make -j4 in the commit
message. There are 55 toplevel texi documents, and they can now all be
processed in parallel.  Before, each directory had to be done
sequentially, reducing the amount of parallelism.

The comparison is not 1-to-1 though. The current doc build doesn't
build the snippet document in multiple languages, even though there
are translations in german, spanish and french, and until now, I've
been building PDF files in cs too.
