Generally a crosscompiler produces "identical" stuff with the native 
compiler... BESIDES when runs that
'*gcc -dumpspecs' to produce the 'specs' !   This is one of the mistakes 
people usually do, they trust the
cross-compiler produced 'specs' to work on the native system too!

So I would check this "stupid mistake" :-) first  !

A GCC made using just the same value for the $host and the $target 
SHOULD be a native GCC and
SHOULD search the native places, UNLESS the 'specs' tells it being a 
cross GCC !

Just try to reproduce the 'specs' where it is installed via the 'gcc 
-dumpspecs > specs' and see what
happens....
