GHCi is too verbose on -v0

[SimonHengel]

Steps to reproduce:

sol@x200:~$ ghci -v0
Prelude> :set -packageghc

I'd expect that nothing is printed, but the following is printed instead:

package flags have changed, resetting and loading new packages...

Currently this is not really an issue for me. I stumbled upon it while investigating #7138.

Thanks for the report.

    Respect verbosity for "flags changed" message (#7139)
    
    Also, print that message on stdout.
