  Changed paths:
    M llvm/lib/Analysis/TargetLibraryInfo.cpp
    M llvm/test/Transforms/InstCombine/sprintf-1.ll

  Log Message:
  -----------
  Disable LibFuncs for stpcpy and stpncpy for Android < 21

These functions don't exist in android API levels < 21. A change in
llvm-12 (rG6dbf0cfcf789) caused Oz builds to emit this symbol assuming
it's available and thus is causing link errors. Simply disable it here.
