Can have no source code in target directory, causing cryptic error msg

Pointing at a build directory instead of a source directory, you can get in a situation where eosfactory find "source" files:

srcs = config.getContractSourceFiles(contract_dir)

However, what is has found is just the .abi file. As it proceeds, it tries to compile the sources:

    objectFileList = []
    extensions = [".h", ".hpp", ".hxx", ".c", ".cpp",".cxx", ".c++"]
:
    for file in srcs:
        if not os.path.splitext(file)[1].lower() in extensions:
            continue

The .abi file is not is srcs, so it is skipped, and this line is never reached:

        objectFileList.append(output)

Thus, the following command_line has an empty element:

    if not compile_only:
        command_line = [
            config.getEOSIO_WASM_LLVM_LINK(),
            "-only-needed",
            "-o",  workdir + "/linked.bc",
            " ".join(objectFileList),
            config.getSourceDir() + "/build/contracts/musl/libc.bc",
            config.getSourceDir() + "/build/contracts/libc++/libc++.bc",
            config.getSourceDir() + "/build/contracts/eosiolib/eosiolib.bc"
        ]

That missing element causes the following cryptic error:
