dev-libs/ntl: set NATIVE=off again.

Pong. NTL detects CPU features at build time, and needs something like
CXXFLAGS="-march=native" to do it properly. But, so long as we don't try
to enable anything based on the user's CPU_FLAGS_X86, it should be safe
to leave NATIVE=off to avoid overriding his CXXFLAGS.
