* Now supports building examples with `--example <name>`.

The default-linker-libraries flag requires a change in the rustc target

The muldefs flag isn't necessary anymore. I think the removal of static
libs (ex. linker fix and pthread_3ds) might have fixed this issue.
The __3DS__ flag doesn't seem to have been necessary at all.
Similarly, `-Z unstable-options` isn't needed for cargo.
