Any user can now trivially build any number of Haskell packages with
`-split-sections` by using `splitSections`/`splitSectionsIf` on any
existing or new flavour:

    -- build all packages but the ghc library with -split-sections
    splitSections :: Flavour -> Flavour

    -- build all packages that satisfy the given predicate
    -- with --split-sections
    splitSectionsIf :: (Package -> Bool) -> Flavour -> Flavour

See the new section in `doc/user-settings.md`.
