Just some thoughts on what might help to further track the issue down if 
nobody comes up with a suggestion on how to solve this right away:

distro-configs/LibreOfficeLinux.conf contains `--without-system-jpeg` 
which means that the system jpeg shouldn't be used during the build. You 
could try whether adding `--with-system-jpeg` to force the system one 
makes any difference (helps to workaround the issue at least).

Otherwise, one way to further track the issue down might be to see 
whether a build without `--with-distro=LibreOfficeLinux` works, and if 
so, add the (potentially relevant) autogen options from the 
above-mentioned distro-configs/LibreOfficeLinux.conf one after the other 
to see which one is triggering the problem.
