Thanks for the additional research! I guess the next steps are:

 - Report the bug to binutils upstream

 - Identify if there is a work-around. But while for gcc issues we
   often work-around by disabling optimizations, for binutils it is not
   always possible to find a simple work-around.

If there's no workaround, then we can add a
BR2_TOOLCHAIN_HAS_BINUTILS_BUG_xyz Config.in bool and add the
appropriate dependencies.

Best regards,

Thomas
