libiconv-osx is borken on macOS 10.12 Sierra #18461

GHCi, version 8.0.1: http://www.haskell.org/ghc/ :? for help
<command line>: can't load .so/.DLL for: /nix/store/xc80lqlb3k0xfh0n5zrpc4i29cllc141-libiconv-osx-10.9.5/lib/libiconv.dylib (dlopen(/nix/store/xc80lqlb3k0xfh0n5zrpc4i29cllc141-libiconv-osx-10.9.5/lib/libiconv.dylib, 5): no suitable image found. Did find:
/nix/store/xc80lqlb3k0xfh0n5zrpc4i29cllc141-libiconv-osx-10.9.5/lib/libiconv.dylib: malformed mach-o image: symbol table underruns __LINKEDIT)
(I could not reproduce the error with other programs that depend on libiconv-osx.)
Looking at the sources of dyld-360.22, which ships with 10.11.6, I don’t see this kind of error message, so, I guess, it’s a new check added in Sierra. I’m trying to figure out what’s wrong with the dylib. This binary comes straight from Apple, right? Which makes things even more strange. Does anyone happen to know where to get the sources of new dyld?
