[Haskell-cafe] Partial statical linking

[Edward Z. Yang]

libgmp and libffi are external libraries not associated with
Haskell, so I don't think -static (which is for Haskell libraries)
applies to them.  You'll have the same problem with any other
sort of library of this type, like libdl and friends ;-)
