Makefile.in (stmp-fixinc): Use tooldir instead of gcc_tooldir.

[Jim Wilson]

I have checked in this patch.

This fixes a cross compiler build for a vxworks target, using the
--with-headers configure option.

When trying to compile libgcc2.c, gcc gives an error message about not being
able to find some header files.  I can't find them because the header files
are in $tooldir/sys-include, and $tooldir is relative to $libsubdir, but
$libsubdir doesn't exist yet.  There is code in the Makefile to create
libsubdir in this case, but it didn't work because it too was trying to
use libsubdir relative pathnames.
