New description:

 Several people have reported that recent `ghc-8.0` and `master` snapshots
 fail to build on OS X,
 {{{
   HC [stage 1] ghc/stage2/build/tmp/ghc-stage2
 Warning: -rtsopts and -with-rtsopts have no effect with -no-hs-main.
     Call hs_init_ghc() from your main() function to set these options.
 Undefined symbols for architecture x86_64:
   "_stg_sel_17_upd_info", referenced from:
       _s1s8Z_info in UI.dyn_o
       _s1s9w_info in UI.dyn_o
 ld: symbol(s) not found for architecture x86_64
 clang: error: linker command failed with exit code 1 (use -v to see
 invocation)
 `gcc' failed in phase `Linker'. (Exit code: 1)
 }}}

 These were originally introduced in #11155, although this appears to be a
 much different beast from the original issue that ticket was reporting:
 the symbols in question here are updatable selector closures, not
 application closures like in #11155.
