DIFF: https://github.com/llvm/llvm-project/commit/0ffe270d0e1dadc3e16f8fa79882fc3b31d28559.diff
LOG: [ELF,test] Remove unneeded -o /dev/null
When the script has executed `cd %t`, it is fine to to use the output
file `a.out`.
(We don't want to rely on lit's default PWD to support lit compatible
runners. Therefore -o /dev/null is used when PWD has not been changed
to a %t derived path.)
