Comment (by bgamari):

 Sadly using `ld.bfd` (on FreeBSD 11, just as in comment:41) fails even
 earlier in the build with undefined DTrace symbols:
 {{{
 /usr/home/ben/bin-
 dist-8.6.1-FreeBSD/ghc/rts/dist/build/libHSrts_thr_p.a(RTS.thr_p_o): In
 function `traceTaskMigrate':

 /usr/home/ben/bin-dist-8.6.1-FreeBSD/ghc/rts/Trace.h:868:0: error:
      undefined reference to `__dtrace_HaskellEvent___task__migrate'
     |
 868 |     dtraceTaskMigrate(serialisableTaskId(task), (EventCapNo)cap->no,
     | ^
 }}}

 I suppose I will also need to disable DTrace.
