Geoffrey McRae 6b5842d2ff [host] cmake: use -march=nehalem by default
Nehalem is the minimum requirement for the host application as it makes
use of SSE4.1 instructions, as such we should default to compling with
it instead of `-march=native` so that when the binary is distributed it
will operate on foreign systems.

Fixed #416
