Make linkerprivate work for ARM and PPC. Testcase covers
all Darwin targets; could be split into separate tests for the chip subdirectories, but from Chris' last mail on testing I assume he'd rather have only one test. Generic seems to be the best available, maybe there should be a Darwin subdirectory? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79877 91177308-0d34-0410-b5e6-96231b3b80d8
