The 'make install...' failed and it took me some time to understand the
reason. For the cross-compilation on the i386 system I have had to build
like this:

# cd /usr/local/acerC720/src
# mkdir /usr/local/acerC720/obj-amd64
# MAKEOBJDIRPREFIX=/usr/local/acerC720/obj-amd64
# export MAKEOBJDIRPREFIX
# make buildworld  TARGET=amd64 TARGET_ARCH=amd64
# make buildkernel TARGET=amd64 TARGET_ARCH=amd64 

If you later use the obj-tree on the bootet 64 bit system to install into the
new disk, one must set the MAKEOBJDIRPREFIX to

MAKEOBJDIRPREFIX=/usr/local/acerC720/obj-amd64/amd64.amd64

and all will be installed fine.
