It's strange that -O2 enables "-fomit-frame-pointer", but -Os doesn't. 
Because I build gdb with "-Os" to work well, but gdb will also crash 
when built with "-Os -fomit-frame-pointer".

This patch can only be used for trunk (4.7), but no gcc4.6 branch. I 
don't know whether there is another better method to solve the issue.
