Naive question: is it possible to effectively run it via emulation?

I miss if the test suite is effectively run somewhere?  And "baseline"
package build means the package built for generic architecture, right?


Cheers,

PS:
My questions are coming from Julia packages in mind, where the test
suite is the only way to know all is fine.  And many times, add System
Image for Julia had been discussed and basically this System Image is
precompilation (generic one or specialized for micro-architecture).
Therefore, maybe this new 'tune' transformation would fit the bill.
