[PR PATCH] [WIP] [RFC] cross-arm-none-eabi rework

[voidlinux-github@inbox.vuxu.org]

[-- Attachment #1: Type: text/plain, Size: 1061 bytes --]

There is a new pull request by sirikid against master on the void-packages repository

https://github.com/sirikid/void-packages cross-arm-none-eabi
https://github.com/void-linux/void-packages/pull/11571

[WIP] [RFC] cross-arm-none-eabi rework
I reworked cross-arm-none-eabi package and now I need some feedback from community.

Why:
- More granular updates — each component of the toolchain can be rebuilt and updated separately.
- Extensive use of template system features — less manual work and less mistakes.

Why not:
- Additional points of failure. Possible solution: arm-none-eabi [build helper](https://github.com/void-linux/void-packages/blob/master/Manual.md#build-helper-scripts).
- More packages in the repo with strange prefixes — this can confuse newcomers.

Please write your thoughts if you are interested in this package or in cross compilation in general, because I don’t even know if anyone except me needs this rework.


A patch file from https://github.com/void-linux/void-packages/pull/11571.patch is attached
