That depends on your intended audience.  One of the criticisms of our
(Earnie's) GCC-4.8.1 build was that it would generate code which could
not be run on older hardware.  If you value supporting users who still
run older hardware, maybe don't set -march so restrictively.

FWIW, I built GCC-4.8.2 with "-march=i586 -mtune=generic", to ensure
default code generation for any vintage of Pentium class CPU.  You may
choose a more recent CPU class, but the price is reduced accessibility
to your application, for users of older hardware.
