I am not able to reproduce this from the current gcc-3.3.x sources. 
Looking at the sources, I don't see how this could have happened.

There is a macro SETUP_FRAME_ADDRESSES that calls 
rs6000_aix_emit_builtin_unwind_emit.  This function is defined only if 
TARGET_AIX is true.  This macro is only defined for aix and 
powerpc64-linux targets, both of which define the TARGET_AIX macro.  It 
should not be used for a powerpc-linux target.

You should check your build tree to see what happened.
