There are some choice words about this part that I will spare the room

[citation needed]: no OPTIONS exist, amongst other things.

Ultimately this doesn't make sense. This port has one purpose, for 
providing a bootstrap toolchain to build the full lang/rust or the 
tarball outside of the ports framework. "Appliance or iterative builds" 
fall under the general purpose category. Not only is there a "circular" 
dependency on the full lang/rust to bootstrap this port, but both 
rust-std and cargo are built regardless and are required for the 
toolchain to work at all; neither are light or minimal by any means. 
cargo especially uses many dependent crates that use the FFI to link to 
libraries provided by other ports or base or bundled. Finally, the built 
results are installed/staged into a special bootstrap hierarchy, and not 
a more "standard" one, for which the singular use case could not be more 
obvious.

Why was rust@ conveniently bypassed here?
