Comment (by kenneth.f.cunningham@…):

 and just installed a fresh copy of clang-3.8 on the same machine running
 10.11.5 -- and it works perfectly without modification, and with what
 would appear to be the exact same output from otool . So it would seem to
 be a SnowLeopard thing, I guess.

 {{{
 $ clang hello.c -o hello
 $ ls
 hello   hello.c
 $ ./hello
 hello world

 $ otool -L /opt/local/libexec/llvm-3.8/bin/../lib/libLTO.dylib

 3.8.0)
