Uh, no. The /lib/cpp symlink is only created *after* GCC is installed,
and keep in mind many, many people build LFS and do not have problems
with its nonexistence up to this point. You must keep in mind that many
times, the last error you see (in this case a complaint about /lib/cpp)
is often times just an end result of some previous, frequently unrelated
problem. This case is no exception. Earlier in config.log we see:

The real problem is that it's not finding the libc startfiles or basic
headers, which usually points to a problem either with the linker or
GCC's specs file. What happens if you do:
echo 'main(){}' > dummy.c
gcc dummy.c
readelf -l a.out | grep interpret
