  #1:  Have you removed the links to newlib?
         If not, rm them.
  #2:  Are the old newlib headers left over in $prefix/$target/sys-include?
         If so, zap them.
  #3:  Is there a file called COPIED in $prefix/$target/sys-include
         The headers are copied over at configure time, and this file is
    then created to indicate it has been done.  If there was one left
    over from your attempts with newlib, it would be noticed by configure
    when you tried again with the linux headers, and the result is that
    the linux headers wouldn't get copied.  So get rid of that one too.
