Is it that much of overkill?  Also that means people have to start  
porting
libelf and bfd for their targets.  Why have duplication when  
something already
exists to get rid of it?  Also BFD can be used as the wrapper so you  
don't really
need to add another duplicated files in GCC to read another file format.

Also maybe Mark could answer the question, why he decided on using  
libelf without
really looking at alternatives?
