The next thing to do is to amend our GCC specs file so that it points
to the new dynamic linker. A simple sed will accomplish this:

-SPECFILE=/tools/lib/gcc-lib/*/*/specs
+SPECFILE=/tools/lib/gcc-lib/*/*/specs &&
sed -e 's@/lib/ld-linux.so.2@/tools/lib/ld-linux.so.2@g' \

unset SPECFILE
We recommend that you cut-and-paste the above rather than try and type it
