  Triple: Fix handling of macos with unexpected target arches (#75469)

Some tools with a specified target arch, but no full triple default to
the host triple. On macos hosts, this would then force using macho on
targets that didn't expect it, resulting in assertions.

We should also probably emit explicit errors if the object format is
specified on targets which don't handle it.
