[gentoo-dev] force verbose build log as per PMS policy?

[hasufell]

We already had a discussion about cmake-utils.eclass and forcing verbose
build log for that which was approved:
http://archives.gentoo.org/gentoo-dev/msg_ce7d33748936663e84a5463fbf7f4d39.xml

Also we have bug https://bugs.gentoo.org/show_bug.cgi?id=384193 and
https://bugs.gentoo.org/show_bug.cgi?id=379497

I opened a tracker https://bugs.gentoo.org/show_bug.cgi?id=429308

Some devs seem unsure about that or want to have a council vote on that

When I sum that up again...
- we are on gentoo and need as much information as possible for
backtracing, resolving bugs, checking whether CFLAGS and such have been
respected
- no need to tell the user to recompile with
EXTRA_ECONF="--disable-silent-rules" or similar just to be able to help him
- some QA checks might depend on verbose build log and are not yet
implemented therefor
- if people want nice build _output_ (not log), they can use --quiet-build
