well, normally make check is run without V=
and if someone once in a while need to run it in verbose mode,
he/she can tolerate it since it's a verbose mode after all.

Hiding message behind V=XX is going to make us remember/recall
at which verbosity level one needs to run tests to get needed
diagnostic info.

I'd rather keep it as it is now.
