a problem when adjusting tool chain

drowsyboy

I meet a problem when adjusting tool chain
asking for help

when executing "SPECFILE='gcc --print-file specs' &&
sed 's@ /lib/ld-linux.so.2@ /tools/lib/ld-linux.so.2@g' $ $SPECFILE > tempspecfile &&
mv -f tempspecfile $SPECFILE &&
unset SPECFILE"

it says " sed cann't recongize --print-file"
Then what can I do?

any help will be helpful......
Thank you!

sed -e 's@ /lib/ld-linux.so.2@ /tools/lib/ld-linux.so.2@g'  \
    $SPECFILE > tempspecfile &&
