This is a more full featured version of ``--allow-undefined``. The semantics of the different methods are as follows: report-all: Report all unresolved symbols. This is the default. Normally the linker will generate an error message for each reported unresolved symbol but the option ``--warn-unresolved-symbols`` can change this to a warning. ignore-all: Resolve all undefined symbols to zero. For data and function addresses this is trivial. For direct function calls, the linker will generate a trapping stub function in place of the undefined function. import-functions: Generate WebAssembly imports for any undefined functions. Undefined data symbols are resolved to zero as in `ignore-all`. This corresponds to the legacy ``--allow-undefined`` flag. The plan is to followup with a new mode called `import-dynamic` which allows for statically linked binaries to refer to both data and functions symbols from the embedder.
