 In 2d2650bf65da3aede4e1c1ca4da623092b869dbe and subsequent commits
 (between 7.6 and 7.8) these settings fields became "C compiler link flags"
 and "ld flags". (I think, more or less.)

 The real problem is that Cabal still looks for the settings fields "Gcc
 Linker flags" and "Ld Linker flags". I guess this should be updated on the
 Cabal side though. (They are empty on at least Linux x86_64, which I guess
 is why nobody noticed before.)
