Have you tried without MAKEOBJDIRPREFIX? Or:

% export MAKEOBJDIRPREFIX=/home/rumrunner/midlertidig/kryssobj
% make buildworld TARGET=i386 TARGET_ARCH=i386

Have you tried with setting SRCCONF and __MAKE_CONF to /dev/null?

What version are you running (uname -a) and what version are you trying
to build?
