OK.  I will adapt my patch accordingly and remove luatex from the
`configure` script.  Jonas can then select whatever he thinks is
appropriate.  I'm too tired to defend superior typographical output

I think a `configure` option is not necessary since the selection of
the TeX engine can already be controlled by the environment variables

Again, I'm too tired to argue.

My idea is that building the documentation works 'out of the box', at
least regarding the used TeX engine.  For example, there are a lot of
users who set the `PDFTEX` and `PDFLATEX` environment variables by
default in their environment variables because they prefer to use,
say, XeTeX for all docuents – in LaTeX, there are *really* differences
depending on the engine.
