 So I think the decision is that we should only require that relative paths
 exist, not absolute paths. Ticket #262 covers checking that libs, and
 headers can actually be found.

 We should check that the configure flags `--extra-lib-dirs=`, `--extra-
 include-dirs=` do point to directories that actually exist.

 The only other improvement we could make would be to somehow notice that
 joining two adjacent components of a directory field with a space form a
 valid absolute path that actually exists, when both components do not, and
 in such a case suggest that the user perhaps meant to use a path with an
 embedded space in which case they must use "" Haskell String syntax.
