Comment (by barracuda156):

 Replying to [comment:15 kencu]:

 when our MacPorts cctools assembler was changed to "do  the right thing"
 by default.

 In my humble opinion, the baseline case should be using Apple own
 assembler as it exists for each OS. Using `clang` may be desirable
 generally on Intel, but every system should be able to function with OS
 tools + gcc.
