make clean does not work

make clean fails in current trunk as it expects old style directory layout.

$ make clean
make[1]: Entering directory `/home/smoser/src/euca2ools/trunk.dist/euca2ools'
make[1]: *** No rule to make target `clean'. Stop.
make[1]: Leaving directory `/home/smoser/src/euca2ools/trunk.dist/euca2ools'
make: *** [clean] Error 2
$ echo $?
2

package builders (ubuntu) often call make clean, and expect it to pass.

Ubuntu is currently carrying the following:
