Hi,

I've figured out all the right flags to pass to a cross-build
environment. Namely:

        env CROSS_BUILD_TESTING=YES
MAKEOBJDIRPREFIX=${X_MAKEOBJDIRPREFIX}      \
            make ${BUILD_FLAGS} TARGET=${TARGET}
TARGET_ARCH=${TARGET_ARCH}     \
            ${X_TARGET_CPUTYPE} KERNCONF=${KERNCONF}
DESTDIR=${X_DESTDIR}       \
            KODIR=/boot/kernel.${KERNCONF}/
         \
            KMODDIR=/boot/kernel.${KERNCONF}/
         \
            __MAKE_CONF=/dev/null SRCCONF=/dev/null
         \
            LOCAL_DIRS="${LOCAL_DIRS}"
         \
            LOCAL_TOOL_DIRS="${LOCAL_TOOL_DIRS}" $1
         \

.. ignore LOCAL_TOOL_DIRS, I haven't committed that yet to -HEAD.

If someone would like to update picobsd to make this work, I'll
happily test out patches and commit it to -HEAD.

Building -8 and previous needed some extra hacks (eg
TARGET_BIG_ENDIAN) which have been removed from -HEAD/-9.

Good luck!
