Update crosstool-ng 1.25 to 1.26

[VirtualTim]

I'm not 100% confident in what I've done here, as this is my first time working with the project.
I mainly just ran ct-ng upgradeconfig, and updated the dockerfiles.

Fixes #816

Is anyone able to help me investigate the CI failures?
I don't see any failures or errors in the logs, it just stops?

Feels like a timeout in the build. Let me try to restart it.

Thanks @JonasVautherin
But now some runs are failing with:

Error: Unable to download artifact(s): Artifact not found for name: cache
        Please ensure that your artifact is not expired and the artifact was uploaded using a compatible version of toolkit/upload-artifact.

Thanks for your contribution, but could you separate it into smaller PRs ? ^^

A few comments on linux-arm64:
linux-arm64 use glibc, not newlib and glibc bust match to debian's glibc or few lower version
It's not baremetal, it use linux kernel headers
We build openmp lib (LIBGOMP)

Thanks for taking a look @bensuperpc. I'm not really sure how I should go about continuing this PR. I thought/hoped I could just do ct-ng upgradeconfig, but apparently this did not work for linux-arm64. And I don't know how I would go about finding other issues.

Personally, I just want dockcross/linux-arm64 with gcc13, so I'm feeling a little out of my depth here.

I made a PR to update crosstool-ng to 1.26 on linux-arm64, I will do more tests on raspberry Pi 4 and 5 on debian bookworm (Raspberry Pi OS 64 bit): #832
