This is just a guess, since you didn't mention what kernel version you
are trying to build, but those are the same error's i got when i tried
to build TI's original release 2.6.22 on a gcc 4.3 based compiler.
Either upgrade your kernel to 2.6.27, look at Koen's git  for
specific git tag and patches, or downgrade to a 4.2 based compiler.
