[Build-common-hackers] recommending verbose build logs

[Matthias Klose]

It's always interesting to look at build logs, or to receive bug reports of the form

  CC
  <compiler error message>

or

  CCLD
  <linker error message>

without knowing how the compiler or the linker were called.  Maybe it is
convenient for a package maintainer watching the build scrolling by (some of
these are even colorized), but lacking this kind of information in the first
place seems to be the wrong thing.  So please let us deprecate this anti-feature
and recommend verbose build logs by default and only turn them off by request
(e.g. with DEB_BUILD_OPTIONS=noverbose).

The only reason (I know) for for needing quiet builds logs should be handled
depending on the buildd (e.g. if sending/emailing a large log is unreliable).

The majority of quiet build logs comes from cmake based systems and (newer)
automake based systems, so maybe this could be handled by cdbs and debhelper for
the majority of packages.  Other proposals how to include the important
information would be welcome.

I would like to see a finalized proposal as a "soft" release goal, or a release
recommendation.
