MIPS r6 is quite different with the previous version.
It use some new target triples:
mipsisa32r6-unknown-linux-gnu
mipsisa32r6el-unknown-linux-gnu
mipsisa64r6-unknown-linux-gnuabi64
mipsisa64r6el-unknown-linux-gnuabi64

This patch has been tested with Debian Port for mips64r6el,
and the support of these triples also is included in llvm:

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @michaelwoerister (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

This is only necessary if the target is available thought rustup.

rustup looks so great.

If possible, I wish that we can support r6 with it.
How these binary is built? by cross or qemu?

r? @alexcrichton, would you mind taking a look at this?

Just checking: as I understand, there are six triples, not four. Is there a reason to include some and not others?

The others are N32. I don't add them here due to that the N32 for mips64el/mips64, aka pre-r6, is not included in rust now.

If we'd like to support N32, it may need some other patches.

The baseline of r6 doesn't enable MSA, since some IP maybe doesn't support MSA.
