added gcc8.1 for Arch & Ryzen 2000 series

[Daniel451]

I have added an arch-linux directory, putting updated copies of kill-ryzen.sh and buildloop.sh for gcc8.1 there. This worked for me with Ryzen 7 2700X and Arch Linux as well as Ubuntu 18.04 LTS.

• minor updated for readme

This was necessary to run on my Ubuntu 18.04 + Ryzen 2700x.
Everything was fine, 3 hours run, with this pull request code and using arch folder.
This fixed the issue #28 I reported earlier.

+1 on merging this and I'll tell if anything different happens on a longer run later.

[leodutra]

@m-r-s Yes. I know that.
But this is an open source unlicensed code and there's not much I can do but
use the original repository for communicating with other interested people.

If you license this... community could keep going on.
Have you thought about that?

[suaefar]

Does this help? Feel free to improve the script. But remember that you need someone with a faulty CPU to confirm that the version with your modifications actually works (i.e., detects faulty CPUs).

[leodutra]

Awesome. Please... keep this PR.
This is being referenced in some community + AMD forum conversations and anyone with 2700x will be able to test and maybe find a faulty 2700x.

Mine is able to run this PR but let's have some more confirmations.

[leodutra]

PLEASE READER, if you own a Ryzen 2700x able to pass this test without issues... please give a 👍 in this. Or 👎 if the test caught any segfault.

This way we will be able to know this test catches any fault.

Just so you know, I'm keeping an updated version of ryzen-test that you can have a look at: https://github.com/Oxalin/ryzen-test

It is using GCC 7.2.0, but it could be updated to 8.1 or 8.2 if needed. @Daniel451 , I'm using a Ryzen 1XXX here, so if you could give me an update on my branch with your 2700X, that would be appreciated.

[leodutra]

I will as soon as I get back to home.

Okay, I will leave this PR open
