Comment (by snoyberg):

 Yes, the problem is that the GCC toolchain that ships with GHC 7.10 does
 not itself use response files internally when calling itself for linking.
 We diagnosed this here, including a short-term (hacky) fix:

 https://github.com/commercialhaskell/stack/issues/795#issuecomment-134758338

 In order to get this included in GHC 7.10.3,
 https://ghc.haskell.org/trac/ghc/ticket/10726 has been set to merge
 status. Once that's backported, the ghc-7.10 branch should just work.
