Comment (by ohho):

 I have tried various link options in `settings` file.

 It seemed that, set an empty "C compiler link flags", i.e., remove "`
 -fuse-ld=gold`", it fell back to the plain-old `/usr/local/bin/ld`, then
 the whole thing worked without any problem.

 I don't know which side to blame, GHC or GCC?

 P./S. I ktrace'd both settings to make sure:
