Hey, have you tried to build the tools first?
this is how i build successfully on mac, not for vax though. But you 
should be able to exchange evbarm and aarch64 with wax, and i guess 
GENERIC for kernel
The outcome will end up in the /tmp/net folder...
./build.sh -U -O /tmp/net -j10 -m evbarm -a aarch64 tools
./build.sh -U -u -O /tmp/net -j10 -m evbarm -a aarch64 tools
./build.sh -U -u -O /tmp/net -j10 -m evbarm -a aarch64 kernel=GENERIC64
./build.sh -U -u -O /tmp/net -j10 -m evbarm -a aarch64 build
