4790959938 Use -fno-plt 
We dont need the PLT and it frees up some registers

33249c872f Use a better default march for binary builds 
x86-64-v2 implies SSE4.2 which should be available everywhere by now. We
will see if we get errors with it.

fe2cd543ba Switch to same algorithm for 128bit SIMD as used for 256 bit SIMD 
Avoids needing to write to the haystack and also less chance of a bug in
the never tested simd since all CPUs I have access to have AVX2
