There's a bug with ocamlc that uses "char*" instead of "const char*" for global string variables. This causes g++ to be very noisy when linking ocamlc programs. That's why the ocaml test used to cat to /dev/null. ocamlopt doesn't have this problem, so we can get rid of the >/dev/null, which may obscure some problems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80968 91177308-0d34-0410-b5e6-96231b3b80d8
