Ubuntu soft links a bunch of binaries in /usr/bin to softlinks that live in /etc/alternatives/ When hitting any of these alternative softlinks execve would fail if the host also didn't have the same softlink paths. Allows us to correctly follow the symlinks on execve as well which fixes launching wine directly from the wine symlink. Alternatively you could have launched /usr/bin/wine-stable directly. Also fixes FEX strace again.
