build: provide guide for compiling node binary with optimizations

[eljefedelrodeodeljefe]

See this discussion nodejs/node#2948

First we would need to collect a list of optimization options and derive some tactics from it. E.g. some configurations won't pass tests.

Options (WIP)

• (use musl)
• disable openssl
• use a shared zlib
• no icu: --with-intl=none
• go wild with strip
• compile a 32-bit binary
• (...)

👍 good start.

Dragging in @thealphanerd here: How open (or secretive) is the release building process? Is it even part of the tasks of the release group or does jenkins do it all?
I think it might be interesting to add this here, as it could also aid testing. E.g. I still don't know how to properly build on windows, so I can test or alter .msis or build with some of the optimizations. Release building could be somewhat related.

The release process is all public 😄

But I think there is now limited access to the release CI

Ah. Thanks for pointing at it. Haven't found what I was looking for though :)
