Subject: [ruby-core:108414] [Ruby master Misc#18756] make V=1 or Q= for verbose?

Issue #18756 has been reported by jaruga (Jun Aruga).

----------------------------------------
Misc #18756: make V=1 or Q= for verbose?
https://bugs.ruby-lang.org/issues/18756

* Author: jaruga (Jun Aruga)
* Status: Open
* Priority: Normal
----------------------------------------
This is a question about `make V=1` and `make Q=`.
Seeing the code, it seems `make V=1` is for a kind of official use rather than `make Q=`.

https://github.com/ruby/ruby/blob/0bab4c4addef3421f8ff1c45564f4a392b860f15/common.mk#L9-L15

However when I tested how to log between `make V=1` and `make Q=` on the latest master `0bab4c4addef3421f8ff1c45564f4a392b860f15`. Against my expectation, the result was that the `Q=` printed more log than `V=1`. I would attach the log files. Is it intentional?

```
autoconf 
./configure
make Q= 2>&1 | tee make_q.log
```

```
autoconf
./configure
make V=1 2>&1 | tee make_v1.log
```

```
$ diff make_q.log make_v1.log | head -10
19d18
< compiling ./main.c
21d19
< compiling dmydln.c
23d20
< generating id.h
27d23
< generating miniprelude.c
31d26
< compiling miniinit.c
```

I am trying to find which part prints the `...ing <file path>` lines to the log. The lines below might be clue. But I am not sure about it so far due to my limitation of understanding `Makefile` syntax.

```
ECHO1 = $(V:1=$n)
```

https://github.com/ruby/ruby/blob/0bab4c4addef3421f8ff1c45564f4a392b860f15/template/exts.mk.tmpl#L6

```
ECHO1 = $(V:1=$n)
ECHO = $(ECHO1:0=@echo)
```
