As for "make -O", could it be that you were talking literally about
that, i.e. about "make -O=target"? Because I meant "make -O=line",
which AFAIR slows down the build only slightly, and provides the
line-level separation that you want to see. I think using that is a
good compromise.
"make -O=line" buffers all output from one line of the Makefile.
For typical targets with only one command, it's the same as "-O".
