Make build output verbose, as a rule

It is not hard to make output of CMake build verbose

"make VERBOSE=1..."
for ninja it's "ninja -v", and a portable, generator-independent form "cmake --build ... --verbose"

I'm requesting it, because while non-verbose this output looks very tidy https://buildbot.mariadb.org/#/builders/221/builds/36673, it is too quiet

Apparently, the above example was miscompilation, a couple of preprocessor flag were missing, resulting in error at runtime, during mtr tests. But it is not possible to figure out miscompilation from a build output, it is too quiet
