I cannot comment on which distro to use. I have only used Angstrom on
an ARM device.

AFAIK, using bitbake with absolute paths to recipes is a bad thing.
Try 'bitbake helloword-image' instead. Note that it builds an *image*,
not just a helloworld executable.

When you bypass building recipe dependencies with the -b flag, things
may go bad.
As your log shows, the toolchain has not even been built! You can see
that from the line:

To sum up: try 'bitbake helloworld-image'.
