add mips64-gnu and mips64el-gnu targets
With this commit one can build no_core (and probably no_std as well)
Rust programs for these targets. It's not yet possible to cross compile
std for these targets because rust-lang/libc doesn't know about the
mips64 architecture.
These targets have been tested by cross compiling the "smallest hello"
program (see code below) and then running it under QEMU.
``` rust
extern {
fn puts(_: *const u8);
}
fn start(_: isize, _: *const *const u8) -> isize {
unsafe {
let msg = b"Hello, world!\0";
puts(msg as *const _ as *const u8);
}
0
}
trait Copy {}
trait Sized {}
```

The cabi stuff is likely wrong. I just copied cabi_mips source and changed some `4`s to `8`s and `32`s to `64`s. It was enough to get libc's `puts` to work but I'd like someone familiar with this module to check it.
