Ouch!  Looks like you're configuring in the srcdir.  Don't do thaht.

What you're trying to so  do is called a "Canadian Cross" and it is
documented in several places.  

You probably only want --enable-langauges=c, because that's all you'll
need to bootstrap the compiler.  Try it again, configure outside the
srcdir, and check every line of the initial output of configure, very
carefully.
