haskell-suite is not a real package or program. In this context, it's
the name of a "virtual compiler" known to cabal.

The correct command is
$ cabal install --haskell-suite -w hs-gen-iface parsec
The -w flag lets cabal know that you want to compile using hs-gen-iface,
which is a concrete compiler implementing the haskell-suite interface.

Yeah, ideally haddock and hscolor should be just separate compilers,
just like ghc and hs-gen-iface are. The user would then specify in
cabal.config what set of compilers to use for simple `cabal install $pkg`.

Then you may be also interested in Ariadne :)
