For a weak symbol func in a comdat, the actual leader symbol ends up named like .weak.func.default*. Likewise, for stdcall on i386, the symbol may be named _func at 4, while the section suffix only is "func", which the previous implementation didn't handle.
This fixes unwinding through weak functions when using -ffunction-sections in mingw environments.
