Request: Complete ISA support

[mcandre]

Hi,

I appreciate the dedication to getting toybox Docker images published for a wide variety of platforms.

Noticed some interesting quirks with the platforms posted for the toybox image.

• linux/amd64/v2 is missing. This more modern variant of linux/amd64 enables additional performance optimizations compared to generic linux/amd64.
• linux/arm64 appears to be the more canonical name for linux/arm64/v8. What do you think about renaming this platform?
• Will we ever see MIPS (e.g. linux/mips64) ports for toybox? These help to model embedded devices such as networking equipment.

I don't currently have an easy means of building for this target. Do you know of any benchmarks that show it's actually worth supporting, preferably ones specific to Toybox?

Also note that container ecosystem support for variants of anything other than linux/arm/v* is still very nascent.

They are (currently) identical; I choose to be explicit, and most of the ecosystem chooses to be implicit instead. Neither is really more or less correct.

Unfortunately not -- MIPS as a platform is honestly very near complete death in my experience (https://www.debian.org/releases/trixie/release-notes/issues.en.html#mips-architectures-removed for example).
