Actually I think it is inherently wrong to enable
CONFIG_USE_PRIVATE_LIBGCC by default.

This option is intended as a workaround for broken toolchains, until
these get fixed.  By enabling this by default, we miss do not notice
the problems our tool chain has, and therefore these never get fixed,
i. e. brokenness grows.  This cannot be good.

CONFIG_USE_PRIVATE_LIBGCC should only be an emergency-opt-in, but
never ever a default setting.

Best regards,

Wolfgang Denk
