Description

https://github.com/ruby/ruby-dev-builder/actions/runs/11095200420

$ ruby test_files/cli_test.rb
ruby: error while loading shared libraries: libruby.so.3.4: cannot open shared object file: No such file or directory

And indeed locally I can confirm it's broken (I use ruby-build for convenience, as you can see it just does a bunch of regular build commands):

$ RUBY_CONFIGURE_OPTS=--enable-shared ruby-build ruby-dev -d ~/.rubies   
==> Cloning https://github.com/ruby/ruby.git...
-> git clone --depth 1 --branch master https://github.com/ruby/ruby.git ruby-master
...
==> Installing ruby-master...
-> autoreconf -i
-> ./configure "--prefix=$HOME/.rubies/ruby-dev" --enable-shared
-> make -j 16
-> make update-gems extract-gems install
==> Installed ruby-master to /home/eregon/.rubies/ruby-dev

And that build with --enable-shared is not working, same as on GitHub Actions:

$ /home/eregon/.rubies/ruby-dev/bin/ruby -v

@hsbt (Hiroshi SHIBATA) said he remembers https://github.com/ruby/ruby/commit/1f6d2e77d9be9a5a829e60908d21d621f4e1ceb0 changed something in this area which might be the cause.

Once this is fixed we should also revert https://github.com/ruby/docker-images/pull/107.
