re-generate foo.hsc when dependencies change

[bos]

(Imported from Trac #17, reported by @SyntaxPolice on 2005-10-31)

This relates to building dependency analysis. #15*.

Cabal does not handle dependencies for HSC2HS correctly. For example,
if Foo.hsc has

#include "x.h"

then Foo.hs should get regenerated whenever x.h is modified. However,
Cabal only regenerates Foo.hs when Foo.hsc has been modified.
