Verbose Builds

Goal description

This goal comprises all the changes required to have verbose build logs in Debian when building packages which display:

• optimisation flags enabled, their amount and order
• warning and error flags enabled
• includes, libraries, isystem paths and order
• link order
• compiler features and standards enabled (e.g. C++11)
• which compilers and tools are invoked

This feature to display above should be available across all packages, but not necessarily enabled by-default everywhere (but e.g. enabled on the buildds)

Next Milestone

• File and track issues for packages not enabling verbose builds. https://qa.debian.org/bls/bytag/W-compiler-flags-hidden.html

• Fix debhelper not passing --disable-silent-rules, at least under some conditions. #680686
• Fix debhelper to show how the upstream build system is called. #680687 As an alternative buildds could run with DEB_BUILD_OPTIONS=verbose
• Change Debian policy to recommend or require verbose build logs. #628515
