I was specifically thinking of quieting the compiler lines, along the
lines of silencing the CC lines. That would still provide the per
directory output for some amount of status. (At first I thought of doing
the @echo "Compiling $<" hack, but in retrospect there's probably no use
in that.)
The attached hack doesn't quiet everything, but makes a significant
difference, 1588 lines down to 622, with 347 being make -C (each of
those was a make -j4 after a make clean).
If folks are interested in this I can look at quieting the remaining
output. My intention would be to still output something on entry to a
directory that would take a non-trivial amount of time (like
src/backend). Though if it's very likely that the CMake stuff is going
to happen (is it?) then I don't think it's worth it.
