Flag: target

[steveklabnik]

This issue is part of #125

--target:

Using this flag looks like this:

$ rustdoc src/lib.rs --target x86_64-pc-windows-gnu

Similar to the --target flag for rustc, this generates documentation
for a target triple that's different than your host triple.

All of the usual caveats of cross-compiling code apply.

Should we keep this flag or not?

[steveklabnik]

This seems reasonably important, though I'd like to get target-agnostic docs supported in a better way, so I'm not totally sure.

Maybe do like docs.rs has and allow you to switch between the different types of docs from a drop down menu in the generated code?

Possibly; this deserves its own quest issue. Feel free to open one, and if you don't, I will by Monday.
