Globals with “available_externally” linkage should never be emitted into the
object file corresponding to the LLVM module.
However, AIX system assembler default print error for undefined reference .
so AIX chose to emit the available externally symbols into .s,
so that users won't run into errors in situations like:
clang -target powerpc-ibm-aix -xc -<<<$'extern inline
__attribute__((__gnu_inline__)) void foo() {}\nvoid bar() { foo(); }' -O
-Xclang -disable-llvm-passes
