Comment(by igloo):

 This bit is a rather unpleasant kludge, and will presumably fail with
 packages that use other libraries:
 {{{
 opt `notElem` ["-ldl", "-liconv", "-lm", "-lpthread"]
 }}}

 In `main/DriverPipeline.hs`, `linkBinary` does
 {{{
 pkg_link_opts <- getPackageLinkOpts dflags dep_packages
 }}}
 which ultimately gives us
 {{{
 map ("-l" ++) (packageHsLibs dflags p ++ extraLibraries p) ++ ldOptions p
 }}}

 If you instead use `[]`, instead of calling `getPackageLinkOpts`, on iOS,
 then does that work?
