 So there is no way to add a static linking variant to a downloaded rust
 port.

 The symbols are in the executable (which is already 99% statically
 linked), and mortals can't really force them in there. (I actually think
 you can do it, with a decompiler/dissassembler, but ... not us).

 So what you have to do is make the executable think it finds the symbols
 it wants. That is what the DYLD_INSERT_LIBRARIES feature does -- just jams
 another dylib into the mixture.

 But this doesn't work either as it is, because rust/cargo expect the
 linkat symbol in libSystem.dylib. So that is how the flat namespace force
 helps us.

 In this case.

 The other method, generating a new libSystem.dylib using ld64's "export
 libraries" feature, is probably actually the better one, but more work, so
 I didn't bother.
