Comment (by mopihopi):

 I just installed ld64 with no variants (apparently no variants means to
 use ld64-latest) and it is working now, thanks for the hint!

 I think the +ld64_xcode variant was required at some point in the past
 because the source code had not yet been released for the latest ld64 but
 it was nevertheless required for some ports.  The only way to get it was
 via xcode.  Apparently source was released later but it didn't get
 switched back.

 It would be nice if the clang-4.0 port ensured that it had a new enough ld
 dependency, but if you don't want to use this ticket for that then I am
 fine with closing it, as clang-4.0 is now working for me after manually
 changing the ld64 variant.
