Backing out LD/CC change in makefile-tail. Adding comment in makefile-emscripten

$(LD) is set to $(CC) if $(LD) not set before makefile-tail.
2. In makefile-tail added $(UPFRONT_LDFLAGS) to accomdate emscripten build
   where -lidbfs.js needs to come before files in ld call.
3) replaced wasm builds with wasm_nl builds; removed wasm_nl builds.
