[PATCH 2/3] build: add optional target parameter to quiet variable function

[Jani Nikula]

Sometimes using $@ as the target in the quiet build lines can be
confusing. Accept an optional second parameter in the quiet variable
function to specify the target.

+1 for 1/3, +1 for 3/3. this I did not quite understand (and don't bother
to figure out -- but I trust this works so +1 too)

I'm OK with this, but I wondered about a simpler change: always use $<.
I doesn't strictly make sense to write "CXX  -g -O2
test/make-db-version.o". When is $@ better here?

For compiling C, C++, and elisp $< does seem better. However, for AR and
linking $@ seems like the way to go. $< only prints the first
dependency, which seems silly for them.

We could also remove the default, and have all callers of quiet pass in
$< or $@ or whatever as part of the first parameter. It's more verbose
everywhere, but I think simpler overall.

BR,
Jani.

Since I've got a rebased version of my patch on top of your existing
proposal to add an optional parameter, I guess we'll go with that for
now. For me the hard part to understand is not this change, but how
'quiet' works before the change.

[PATCH 3/3] build: add .deps to CLEAN instead of listing in clean target

[Jani Nikula]

Seems, uh, cleaner this way.
