Previously, tests hardcoded ocamlopt and cmxa, which broke builds on machines without ocamlopt. Instead, they now fall back to ocamlc. As a side effect this fixes PR14727, which was caused by a crude hack that replaced gcc with g++ everywhere in the ocamlopt native compiler path and passes it back using -cc. Now the tests use the same technique as META, i.e. -cclib -lstdc++. It might be more fragile than using g++ explicitly, but it will break when the installed package will also break, which is good. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220828 91177308-0d34-0410-b5e6-96231b3b80d8
