   First, read <URL:http://gcc.gnu.org/ml/gcc-help/2007-06/msg00230.html>.
When running the "ln -s" commands, you want to start with the newest of the
packages; perhaps check the file "configure" in each package, because the
packages gcc, binutils, newlib, gdb, etc. keep the common files and
directories in sync. In this particular case, I think the order should be
binutils-2.18, gcc-4.2.1 and newlib-1.15.

   The files related to libtool were upgraded between binutils-2.17 and
binutils-2.18, but the change first appears in GCC in 4.3.0 (which has not
been released yet). You may have to try with binutils-2.17 instead.
Alternatively, use a GCC 4.3 snapshot. If none of the above works or you're
desparate enough to get the combination of binutils-2.18, gcc-4.2.1 and
newlib-1.15 working, it is necessary to use the libtool version from
gcc-4.2.1 and the libiberty version from binutils-2.18. I.e.

...
$ mkdir combined
$ cd combined
$ ln -s ../gcc-4.2.1/* .
$ rm libiberty include
$ ln -s ../binutils-2.18/* .
$ ln -s ../newlib-1.15.0/* .
...
