Problem is that you have changed the specs of /usr/bin/gcc (which you have installed), while you needed to change those of /tools/bin/gcc (/usr/bin/gcc does not exist when doing "Adjusting the toolchain"). So basically, you've done nothing. And you are still using /usr/bin/gcc, which is broken. Also, since you had not done the soecs change in time, everything compiled after "Adjusting the toolchain" may be flawed. If you have backed up the /tools directory when instructed to do so, you may want to remove everything in /mnt/lfs, then reinstall the saved /tools, and then restart chapter 6. Otherwise, I think you should erase everything and start over (don't forget to back up /tools this time... Also double check that all the sanity check are exactly as in the book).
