Comment (by kencu):

 this is the issue that is leading to the non-zero output that is leading
 the script to think you need -latomic:
 {{{
 ld: library not found for -lc++
 }}}

 Where the heck did your -lc++ go? I think I might have a clue...

 make a little file like this:

 {{{
 % cat test.cpp
 #include <stdint.h>
 uint64_t v;
 int main() {
     return (int)__atomic_load_n(&v, __ATOMIC_ACQUIRE);
 }
 }}}

 and then try to compile it with some verbosity flags added, and see what
 happens... I will guess you have no SDK, but let's see.

 Here's what I get:
