In our case, toolset=darwin, yes.

However, on a 64-bit Mac, this only builds address-model-64.

When I pass address-model=32, I get:

I need to build a 32-bit Context library even on a 64-bit build
machine. Is this possible?

None of them seem to specify address-model, so presumably they're
defaulting to the current architecture. I don't know if they're
running on 32-bit or 64-bit machines.
