Does this happen after a complete 'make clean; make' cycle?

If so, could you attach your Buildroot .config file to the bug?

Thanks!

I built a toolchain based on current buildroot git (more or less 2014.02-rc1),
for arm7tdmi, using binutils-2.23.2, and did not see any problem.

This happens on ARC too when building native binutils.
It's because in uClibc "mbstowcs" is only gets built-in if WCHAR support is
enabled.

So proper fix would be to add WCHAR support in toolchain as a dependency for
native binutils.
