[committed] Fix length computation bug in bfin port
The tester seemed to occasionally ping-pong a compilation failure on the
builtin-bitops-1.c test. I long suspected it was something like length
computations.
I finally got a few minutes to dig into it, and sure enough the blackfin
port was claiming the "ones" operation was 2 bytes when it is in fact 4 bytes.
This fixes the compilation failure for the builtin-bitops-1.c test. Sadly,
it doesn't fix any of the other failures on the bfin port.
Committed to the trunk.
