Many build systems need a drop in replacement for strip as well as objcopy. This change adds a symlink to llvm-strip for llvm-objcopy. The plan is for llvm-objcopy to detect when it was invoked as llvm-strip/strip and to change it's behavoir correspondingly.  See https://reviews.llvm.org/D41100 for details on the whole plan.
