FWIW, that's what CMake does by default. (CMake's implementation is better
though: it also gives the progress percentage and uses color-coding so you
can immediately recognize the different kinds of operations and so the
operations are visually separated from the stderr output.) It is frowned
upon in Fedora because it doesn't allow you to easily check that
RPM_OPT_FLAGS are being used and so our %cmake and %cmake_kde4 macros
include:
-DCMAKE_VERBOSE_MAKEFILE=ON
which overrides this behavior and shows the full command lines by default.
(It's also possible for CMake-using packages to do this at make time with
make VERBOSE=ON which is what was the previous recommendation.)

This will be REQUIRED in Fedora for packages using this feature (unless this
can somehow be set at configure time, in which case our %configure macro
could do it similarly to how our %cmake and %cmake_kde4 macros do).

By the way, it's pretty sad that automake had to reinvent the wheel instead
of using the established VERBOSE=ON syntax.

I agree (and I like how this has been the default in CMake since forever),
but we were told that this is no good for Fedora because we should have the
full command lines in build.log so we can check for the optflags.
