When I came to Chapter 6.10 of LFS6.3 (Re-adjusting the Toolchain),
after typed this command,

gcc -dumpspecs | sed \
-e 's@/tools/lib/ld-linux.so.2@/lib/ld-linux.so.2 at g' \
-e '/\*startfile_prefix_spec:/{n;s at .*@/usr/lib/ @}' \
-e '/\*cpp:/{n;s@$@ -isystem /usr/include@}' > \
`dirname $(gcc --print-libgcc-file-name)`/specs

it told me that
gcc:unrecognized option '-mutune=pentiumpro'

Didn't I compile gcc successfully or I didn't configure it right?
