I've the same problem building an ARM EABI toolchain. The GCC build error happens with buildroot-2009.02 (gcc-4.3.2) and current SVN (25712, gcc-4.3.3). The 
result is equal for xscale, iwmmxt and arm920t.

Ater each change in menuconfg I've deleted the toolchain_build_arm/ subdir. Is this sufficient?
