Applied to master, thanks!

I was going to suggest that instead of adding a configure option to
decide whether to build man pages or not, you could have decided
depending on the availability of xsltproc. Except that, as you
explained in the commit log, xsltproc might be available, but still
building the man pages might fail.

So, I've applied. Hopefully, upstream will accept this solution.

Thanks!

Thomas
