update MIPS toolchain version

[kaspar030]

This upgrades the MIPS toolchain to the latest version.

Supercedes #47.

@kaspar030 do we need to do this if there are plans to remove mips RIOT-OS/RIOT#11788.

Otherwise, I was able to build the image but I have no hardware to test it.

Could you provide some kind of test output?

IMO that's just a suggestion. Removal of mips might happen later if it maintanance doesn't improve.

Ok I re-read the discussion thread, there doesn't seem to be a clear agreement yet.

Since I have no hardware to test

We have a chicken and egg problem. The new toolchain from this PR fails on 2019.04. There's a fix in RIOT-OS/RIOT#11986. Anyhow, travis for this repo will (currently) always use 2019.04.

Ideas? Maybe first switch to 2019.07, then merge #11986, then backport to 2019.07-release?
Please let's not postpone merging this PR until 2019.10...
@MrKevinWeiss, it is "your release", what do you think?

[miri64]

Weren't we thinking about release specific tags for this repo anyways (#64)?

[MrKevinWeiss]

Ya, I think there were a few things that people still wanted in the release, at least @miri64 and @cladmi had some.

I downloaded the MIPS toolchain 2018.09-03 using the link found in the Dockerfile. I did a clean build of RIOT PR #12227, including the diff I mentioned in this PR. The board was printing the correct message over UART.

tested by @francois-berder

ACKing to get that out of the way for sorting out the merge order.

So if we trigger Murdock again, this should work now?

it should!

[kaspar030]

Somehow this exact PR gets scheduled to a travis worker that seems to be hopelessly overloaded...

[benpicco]

The command "eval git clone --depth=50 https://github.com/RIOT-OS/riotdocker.git RIOT-OS/riotdocker " failed 3 times.
$ cd RIOT-OS/riotdocker
/home/travis/.travis/functions: line 109: cd: RIOT-OS/riotdocker: No such file or directory

😕

Now it went through! &go
