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!

17;; Tests that reloc to _MergedGlobals show up as explicit symbol reloc
