All we do is dump the specs, edit it, and pipe it out to where the  
target gcc's specs location is.
All you need to do is remove that file.

$(dirname $(/tools/bin/gcc --print-libgcc-file-name))/specs should  
output the specs file location.

rm $(dirname $(/tools/bin/gcc --print-libgcc-file-name))/specs   would  
remove it.

Or you can go into /tools/lib/gcc/*/* and rm specs.

You may want to remove the old gcc binaries and install from 4.8.0:

GCC has no uninstall target so you can remove in /usr/bin  *gcc* *g+ 
+* /usr/lib/gcc

Just do a: find /usr -name 4.8.0    and see what is around.

Then you can verify you are using the proper gcc from /tools/bin when  
you enter chroot from this point:
Section 8.5 Entering the chroot (if chrooting)
Or after booting if using the booting method. 7.15

If the sanity check fails afterwards, then the specs file may be still  
in /tools

Sincerely,

William Harrington
