Ah, that explains, thanks Khem Raj.
So then I tried:
$ arm-angstrom-linux-gnueabi-gcc -mfloat-abi=soft -o hello.soft hello.c

Apparently, I miss the soft subs. I got the tree above by
MACHINE=beagleboard ./oebb.sh config beagleboard
MACHINE=beagleboard ./oebb.sh update
MACHINE=beagleboard ./oebb.sh bitbake virtual/kernel
I have to figure out how to compile for ABI soft float yet.
Another route would be to use a hard FP roots on my BeagleBones. I guess that
would be a case of copying the Angstrom kernel I build to the BBB. But if so
and how is yet unclear to me. I guess I'll google a bit around.
