Also, http://www.iki.fi/tml/libocon2011-xcompiling.pdf gives an
overview of LibeOffice cross-compilation in general.

Please give more details. (On this list, not in private mail.)

The master branch is obviously a moving target. For a month or so I
haven't attempted iOS compilation, so some slight problem might have
popped up.

(I just tried to run autogen.sh for iOS and indeed noticed a problem
in the checks for libxslt. Will fix up that.)

Well, the DESKTOP flag is more to just avoid wasting time on compiling
completely unnecessary "modules"--- also in the parts that do get
compiled now there surely is lots of stuff that doesn't make sense on
portable devices.

Yup. Something like that should be doable relatively soon, as the
LibreOffice code obviously for such usage doesn't display anything or
require any interactive input. But all the C++ and UNO stuff still
needs to work, of course, and there is lots to do there.
