[host] cmake: use -march=nehalem by default

Browse Source 
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
