I have seen this before.   gcc must be finding the incorrect assembler. 
My belief is that it will try to use ${prefix}/${target}/bin/as if it is
available.   I do not think your command line option will effect this
problem because this error occurs after you have the new
compiler(xgcc).  

Make sure this is the target assembler.  You should be able to find what
assembler it is finding by adding the -v option to gcc.  

I have done exactly what you are trying to do.   Below I wrote some
notes on how to do this.  These notes were mostly for myself.  So, they
are not real clear, but hopefully they will be helpful.
