1.14.0 mips test failures: net "timeouts" tests

[infinity0]

Build machine: https://db.debian.org/machines.cgi?host=mips-aql-01
Build log: https://buildd.debian.org/status/fetch.php?pkg=rustc&arch=mips&ver=1.14.0%2Bdfsg1-3&stamp=1484077706
Raw build log: https://buildd.debian.org/status/fetch.php?pkg=rustc&arch=mips&ver=1.14.0%2Bdfsg1-3&stamp=1484077706&raw=1

This is after applying #38650 and #38675. The LLVM diff between Debian vs Rust is here.

Note that, because of these failures, the whole-compiler tests (e.g. run-pass etc) have not been run, but they probably also have failures.

Seems an ABI mismatch. However I moved (pun semi-intended) recently and my MIPS64 box isn't currently with me so I can't investigate any further at this time.

Triage: Let's close this as obsolete as this issue is now very old and nothing has happened in several years, and it is unlikely something will ever happen.
