when building you should be able to build for a specific target

[filipecosta90]

Example of building on cascade on using a previous gen that does not have the feature ( it would not work ), and the opposite ( building on an old gen and potentially not taking advantage of new gen features ).
Proposed fix:

• stage 2) on the builders spec, when we need to be restrictive of where the build artifacts are going to be ran we add some metadata tag ( example march or something similar )
• stage 3) need to check the tags you're allowed to run. arch=amd64 + (march=icelake,...)
