or

util/abuild/abuild -t thomson/ip1000 $PWD

to build on the top level.

You can also specify a payload directory with -p

mkdir payloads
cp /somewhere/filo.elf payloads
then add a file payloads/payload.sh which prints the name of the payload
to use (and takes the mainboard as a parameter)
such as
echo "`dirname $0`/build/filo.elf"

then you can build a fully working image with payload by specifying:

util/abuild/abuild -t thomson/ip1000 -p ./payloads $PWD

Specify -c max or -c 2 if you have an SMP system, to speed compilation up.
