Hi Dan,

Thanks for the tip.  I haven't got to the bottom of the whole multi-lib
nof problem, but one change that seems a good idea is to make the
following  change in crosstool.sh:

@@ -301,7 +302,7 @@
 echo "We check GLIBC_EXTRA_CONFIG ($GLIBC_EXTRA_CONFIG) to see if it
contains --without-fp to decide."
 case "$GLIBC_EXTRA_CONFIG" in
    *--without-fp*)
-      cp -a ${PREFIX}/${TARGET}/lib/nof/*.so* ${PREFIX}/${TARGET}/lib
+      cp -af ${PREFIX}/${TARGET}/lib/nof/*.so* ${PREFIX}/${TARGET}/lib
       ;;
 esac

On powerpc, if you don't do this, although the nof subdirectory is
there, it fails as the links already exist.

cp: cannot create symbolic link
`/usr/local/powerpc-linux/gcc-3.3.1-glibc-2.2.5/powerpc-linux/lib/libstdc++.so':
File exists
cp: cannot create symbolic link
`/usr/local/powerpc-linux/gcc-3.3.1-glibc-2.2.5/powerpc-linux/lib/libstdc++.so.5':
