    core: remap various architectures
    
    We want to keep these consistent so that they map to external tooling no
    matter what the host system claims. We might need to do this in a couple
    other places in the future, but for now, given the design of Builder, this
    is probably the widest net to cast.
    
    Fixes #1061
    Fixes #1070
