[Buildroot] Error: duplicate .personality directive while building libstdc++ w/ ARM EABI

[Rob Landley]

Did you ever get a reply to this message?  I'm hitting it now on an unrelated 
project and this message is the most relevant google hit that comes up.

Possibly gcc 4.1.2 doesn't properly support arm eabi with C++...
