Subject: [ruby-core:106477] [Ruby master Bug#18374] make: Circular spec/ruby/optional/capi/ext/array_spec.c <- spec/ruby/optional/capi/ext/array_spec.c dependency dropped.

Issue #18374 has been updated by xtkoba (Tee KOBAYASHI).


As for `ruby.pc`, this is due to `--with-ruby-pc=ruby.pc` specified for `configure` argument. Combined with [configure.ac#L4295-L4299](https://github.com/ruby/ruby/blob/1f4af993835219efa8feaf76a0b36252028691f1/configure.ac#L4295-L4299) and [template/Makefile.in#L320-L321](https://github.com/ruby/ruby/blob/1f4af993835219efa8feaf76a0b36252028691f1/template/Makefile.in#L320-L321), this effectively defines a circular dependency:

```makefile
ruby.pc: ruby.pc
```

What is it about? That does not look healthy to me.
