On OpenBSD, the stack-smash protection transform uses "__guard_local" and "__stack_smash_handler" instead of "__stack_chk_guard" and "__stack_chk_fail". However, CodeGen/PowerPC/stack-protector.ll doesn't specify a target OS, so on OpenBSD it fails. Add -mtriple=ppc32-unknown-linux to make the test host-OS agnostic. While there, convert to FileCheck. Patch by Matthew Dempsky. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185206 91177308-0d34-0410-b5e6-96231b3b80d8
