Linker error when compiling for AFL coverage

Hi! I found a curious edge case and made a PoC for it.

This affects the if-watch package.

I have no idea what's happening here. If you or someone else finds a fix please submit a PR. :-)

Well, the issue seems to disappear when removing cdylib from the crate type array, but as to what exactly leads to it, I am unsure. Might be upstream with rust linker?
