Improve instruction for Adjusting Toolchain

[bdubbs@…]

From Robert Connolly:

Rather than:

SPECFILE=`dirname $(gcc -print-libgcc-file-name)`/specs &&
gcc -dumpspecs > $SPECFILE &&
sed 's@^/lib/ld-linux.so.2@/tools&@g' $SPECFILE > tempspecfile &&
mv -vf tempspecfile $SPECFILE &&
unset SPECFILE

I find it cleaner and easier to read:

gcc -dumpspecs | sed 's@^/lib/ld-linux.so.2@/tools&@g' \
    > `dirname $(gcc -print-libgcc-file-name)`/specs

The result is exactly the same.

Thanks Robert. Fixed in r7775.
