We introduce a `pregen-etex` Makefile rule that only build the .etex
files of the manual (whose OCaml examples may be tested and expected
to produce certain outputs), without also building the
standard-library documentation. This is faster than the previous
`pregen` rule as ocamldoc on the standard library was the
bottleneck. On my machine, `pregen-etex` completes in 1.5s-2s, while
`pregen` completes in 6s-7s.
