[Buildroot] Build failure with 2010.08-rc1

[Will Newton]

Hi,

buildroot 2010.08-rc1 is failing to build for me part way through the
initial gcc build.

Which appears to be caused by trying to build gcc without headers. I
assume the configure --with-newlib is intended to build against the
newlib headers? How is this intended to work as by default gcc does
not ship with newlib?
