Document supported hardware architectures

[zamazan4ik]

Hi!

I have checked the documentation but did not find any word about supported architectures - only about supported operating systems.

Could you please put the information about supported architectures to the documentation please? E.e. about supported architectures for different operating systems, some specific requirements to the supported instructions, if you have any (e.g. maybe AVX is required - I do not know).

This kind of information is important for the end-users.

Thanks in advance!

That information is located on https://rethinkdb.com/docs/install/ under "other architectures."

That's pretty incomplete, as you can see. It could describe "unsupported" architectures that are known-working, and actually have some degree of specificity about what combinations have release packages or are known-working. For example, 32-bit x86 might still work (but is not recommended). People still build for 32-bit ARM, I think. Also, MacOS on ARM is known to build and run but doesn't have dmg generation working.

As far as I'm aware, RethinkDB doesn't use special processor features.

Moved to docs repo.

#1344 has some further documentation.

It's not a big table of known-working combinations of architecture and platform, though.
