Comment (by MikolajKonarski):

 Duncan helped me with that one, so I have some hypotheses now. The old GHC
 7.6.3 has no "ld flags" nor "Ld Linker flags" in the settings file, but it
 somehow produces "Ld Linker flags" in the {{{ghc --info}}} output and this
 is what cabal expects. However, GHC 7.8.3 has "ld flags" in the settings
 file and doesn't produce "Ld Linker flags" at all in {{{ghc --info}}}.
 This may be a bug or a half-done transition to another convention, but
 right now it fools the newest cabal. BTW, I can't probably specify "Ld
 Linker flags" manually in the settings file, because it's supposed to be a
 list of options, not a string, as the other options. Perhaps "ld flags"
 was intended to let people extend "Ld Linker flags" manually via the
 settings file? Anyway, it doesn't work right now.
