Have verbose stack log indicate that it was built via cabal-install, and if so, which dependencies were used

[mgsloan]

When installed via cabal-install, stack could potentially exhibit different behavior when compiled with different dependency versions. This sometimes makes it troublesome to diagnose stack issue reports, as it can take a long time to reach the eventual conclusion that a dependency is to blame.

See the most recent instance here - #2182

When run in verbose mode, stack should warn that it was built via cabal-install, and enumerate all the dependencies chosen. This way it's apparent that a difference in dependencies might be a suspect cause of the issue. We may also want a shorter warning when run without -v.

Similarly, when stack is built with stack, we should log which build configuration was used.

In conjunction with #1238, we could also log whether they're using an official binary.

Closing. I'd say this was fixed by #2222 (except for #2450) and that

is (now) tracked by #1238.
