--- Comment #1 from Thomas Petazzoni <[email protected]> 2013-04-25 13:36:58 UTC --- Does this happen after a complete 'make clean; make' cycle?

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

Thanks!

--- Comment #3 from Thomas De Schampheleire <[email protected]> 2014-02-13 15:02:35 UTC --- 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.

--- Comment #5 from Alexey Brodkin <[email protected]> 2014-08-18 15:22:57 UTC --- 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.
