Comment (by kencu):

 I recall now that I left the {{{ld64 +llvmdev}}}  option available so that
 intrepid explorers like me could try that out (it's a devel version after
 all) and see where the errors and issues might arise.

 So I'll leave it in the ld64 port.

 For this, you need to use {{{ld64 +llvm10}}}, which is the well-trodden
 default path.

 I would not think that putting individual fixes into ports using
 {{{install_name_tool}}} to work around this would make any sense.

 I due course, cctools will be updated to a newer version that calls the
 newer llvm-objdump with the proper flags. That is the solution to the
 this, in the long run. I could have patched otool to send the right flags,
 but I did not because other llvm11 issues were also likely I though.
