The output isn't there to amuse you but to give you information for
troubleshooting in case things go wrong. ;-)

I never understood the point of a build process generating incomplete
progress report. Either I wan't all the details (almost always) or
just the final outcome -- something you can do without any patching:

  $ if ! make > /tmp/build.log 2>&1 ;then echo "BUILD FAILED!!!" ; fi

That's actively harmful -- a build failing on you with useless output
is already bad enough, having to re-run the build is annoying on its
own, having to additionally figure out the option that will give you
useful output is almost insulting.

Maybe it's just me...
