`elfhack` fails on the `libgraphitewasm.so` file but doesn't dump any useful info when it does so:

    terminate called after throwing an instance of 'std::runtime_error'
      what():  Error opening file
    Aborted (core dumped)

Apparently that happens [here](https://searchfox.org/mozilla-central/source/build/unix/elfhack/elf.cpp#109). Not sure why this would happen; I'm looking into it.

`elfhack` fails on the `libgraphitewasm.so` file but doesn't dump any useful info when it does so (`Segmentation fault (core dumped)`). I'm not familiar enough with `elfhack` to understand why that might be happening. According to the `README` the library isn't awfully robust especially on non-`libxul` targets, so I guess that shouldn't be terribly shocking.

I assume `elfhack` is making some assumptions about the library that aren't true of `libgraphitewasm.so`. We can either fix `elfhack` so it won't freak out or always skip it for wasm targets.
