When reference types are enabled clang will generate call_indirect instructions that explicitly reference the global `__indirect_function_table` symbol. In this case the resulting global symbol was not being correctly marked with explicit import name/module, resulting in the linker reporting errors when it was referenced. This issue was reported in https://github.com/WebAssembly/tool-conventions/issues/158
