Change CROSSCOMPILE flag to NO_NATIVE_OPTIMIZATION (#3279)

Browse Source 
* Change CROSSCOMPILE flag to NOMARCHNATIVE.

The old name was confusing, the new name describes exactly what it does.

This fixes issue #3272

* Break configuration when using CROSSCOMPILE.

This stops any old build scripts from producing broken builds.

* Use NO_NATIVE_OPTIMIZATION rather than NOMARCHNATIVE.

Addresses @madmaxoft's concerns.
