9;; Ensure no regression on ARM/gcc compatibility for
10;; emitting explicit symbol relocs for nonexternal symbols
11;; versus section symbol relocs (with offset) -
12;;
13;; Default llvm behavior is to emit as section symbol relocs nearly
14;; everything that is not an undefined external. Unfortunately, this
15;; diverges from what codesourcery ARM/gcc does!
