How to build osmocon for the target?

Hello everyone! I'm trying to run osmocombb on Neo Freerunner. Read and hopefully understood http://bb.osmocom.org/trac/wiki/{CalypsoRomloader,osmocon,OpenMoko}. One thing I completely miss is how to build osmocon for the target phone to be able to run ./osmocon -i 13 -m romload -p /dev/ttySAC0 layer1.highram.bin In the source tree, osmocon is built only for the host, and I do not see any configuration options to enable it also for the phone... Thanks in advance, D.
