[arch-haskell] Error messages from FindCLibs

[Rémy Oudompheng]

The FindCLibs function in cabal2arch (which I want to include in the
archlinux library) report errors for non-Haskell dependencies it
cannot translate into ArchLinux package names. Batch running
cabal2arch can find some missing items : I attached a list of
candidates.

We basically have to run "pkgfile lib$i.so" for $i in this file
(pkgfile is a script from the pkgtools package) to know the package
name corresponding to a library name.
