test/tools/llvm-objcopy/ELF/archive-unknown-members.test

## Show that llvm-objcopy and llvm-strip emit errors when attempting to modify
## archives containing unrecognized files, and do not modify anything. We use
## --strip-debug so that the section should be removed, and a difference
## detectable, if the file were modified.
