Update crosstool-ng 1.25.0 -> 1.26.0

[VirtualTim]

crosstool-ng 1.26.0 was released September 2023 - https://github.com/crosstool-ng/crosstool-ng/releases.

It looks like the process could be as simple as updating CT_VERSION, and regenerating all the crosstool-ng.configs.
The release notes mention:

If you're updating an existing configuration from crosstool-ng 1.25.0 make sure to use ct-ng upgradeconfig to pick up some internal changes.

@bensuperpc it looks like you've been handling the previous crosstool updates.
I'm willing to attempt this update, would you be able to guide me through the process?

You have several choices for the update, some images were updated with the "ct-ng upgradeconfig" command and check if everything looks good in the crosstool-ng menu, for others, I took one of the examples provided by crosstool-ng and made the modifications to match the old version (like enable some libs, CROSS_TRIPLE etc...) in the crosstool-ng menu, ct-ng upgrade config doesn't work very well sometimes.

Afterwards there may be some debian packages or commands that have changed, sometimes it is necessary to make some changes in the dockcross-base.

After building the docker image, then test by building a program (like python, stockfish etc... like in CI) and launching it on the target (like on Raspberry Pi 4 with Raspberry PI OS or Ubuntu), if you don't have the hardware, you can use QEMU with an image of a system (Risc-v ect...).

Here is an example to add an image, but the beginning will help you:
