Review request for Asterisk Developers.


Changes
-------

Added a menuselect option and necessary configure tests to check for compiler capability to build with -march=native.


Summary (updated)
-------

The selection of PROC as k8 for -march on 64bit systems can cause gcc to create binaries that will not run on the local machine since it will optimize to use 3Dnow! and extended 3Dnow! instructions where possible.  This type of code shouldn't even really be in the Asterisk build system so I'm ripping it out in its entirety instead of changing k8 to native.  There is now a menuselect option that is available when a version of gcc that supports -march=native is being used to enable or disable tailoring of generated code to the instruction sets available on the local CPU.


This addresses bug ASTERISK-19462.

Ran this through the testsuite and it didn't break anything.
