   Because:
   1) This is what the documentation says you should use.
   2) This is where you will have the header files installed afterwards in
      order for the installed cross compiler to work.
   3) If you have previously built a cross compiler for this target,
      the header files are already installed there.
   4) $(tooldir) is also where you have the cross libraries, cross
      as/ar/ld/ranlib, etc. installed.

   Jeff, please have a look at the documentation, i.e. your favourite
conversion of gcc.texiı. Go to the "Installation" section. Go to the
"Cross-compiler" section. Go to the "Cross Headers" section. Notice how you
are told to install the cross headers in /usr/local/TARGET/include, which,
assuming --prefix=/usr/local, is exactly $(tooldir)/include.

   IMHO it is clearly a bug for the build process to use
$(gcc_tooldir)/include, which does not yet exist, instead of
$(tooldir)/include.
