Comment (by rwbarton):

 Yes, I looked into the cabal linker flags issue too, but forgot to mention
 it, sorry! Indeed there were several changes between 7.6.3 and 7.8 but
 cabal was not updated accordingly. (There was some minor fallout on the
 GHC side also, see #9614.) I think best is to update cabal to parse the
 new (7.8) fields if present and if not fall back on the old (7.6.3)
 fields.
