I'd argue that the library is far more frequently used, given that it's 
used across archs and arm is (for the time being, that seems to be 
gradually changing) still a rather obscure arch (for end-user installed 
distros, anyway), so the neon library is likely the most frequently used.

However you are probably correct about the USE flag, as the library usage 
seems to be required in many cases and thus not USE-flaggable.

So I'd still argue that to prevent confusion... but it's not something I 
feel strongly about, so given no one else objecting, use=neon for the simd 
extensions works as a global USE flag, and if it's ever used for the net-
lib, that one can change I guess.
