Ruby 3.2 is not built with YJIT

[djones]

One of the big benefits of Ruby 3.2 is YJIT. Currently it is not compiled with YJIT support.

When you go to enable it down the line and verify, this is what you get:

docker run -it phusion/passenger-ruby32 ruby --yjit -ve 'p RubyVM::YJIT.enabled?'
ruby: warning: Ruby was built without YJIT support. You may need to install rustc to build Ruby with YJIT.
ruby 3.2.0 (2022-12-25 revision a528908271) [aarch64-linux]
-e:1:in `<main>': uninitialized constant RubyVM::YJIT (NameError)

p RubyVM::YJIT.enabled?
        ^^^^^^

rustc needs to be installed at some point before ruby is built?

confirmed, this is very unfortunate...
