crochet build fails at ubldr Wandboard-Dual

Crochet does use the standard build machinery; the only significant difference is that it builds ubldr separately after a successful buildworld.  Building ubldr separately allows it to reuse the buildworld results when building for multiple boards with the same TARGET_ARCH but varying UBLDR_LOADADDR.

The detailed logic is in lib/freebsd.sh, I’ve pasted it below (with a few variables substituted in and some error checking removed to clarify):

    cd ${FREEBSD_SRC}
    ubldr_makefiles=${FREEBSD_SRC}/share/mk
    buildenv=`make TARGET_ARCH=$TARGET_ARCH buildenvvars`

    cd ${FREEBSD_SRC}/sys/boot
    eval $buildenv make UBLDR_LOADADDR=0x11000000 -m $ubldr_makefiles obj
    eval $buildenv make UBLDR_LOADADDR=0x11000000 -m $ubldr_makefiles clean
    eval $buildenv make UBLDR_LOADADDR=0x11000000 -m $ubldr_makefiles depend
    eval $buildenv make UBLDR_LOADADDR=0x11000000 -m $ubldr_makefiles all

    cd arm/uboot
    eval $buildenv make UBLDR_LOADADDR=0x11000000 DESTDIR=${UBLDR_DIR}/ BINDIR=boot NO_MAN=true -m $ubldr_makefiles install

The last bit here is just a way to get the FreeBSD makefiles to copy the built executable to a known location (otherwise, Crochet has to reproduce the FreeBSD build system logic for determining which objdir layout to use).

Cheers,
