Unfortunately no. It does raise the question of when -Wl should be
interpreted by the clang driver. If we parse it to decide if we are
producing a shared object and don't need to also pass a PIE option, we
should probably also parse it for deciding which crt object to use.

On the other hand, if we don't parse it when deciding which crt object
to use, then the correct behavior is probably to not parse the -Wl
options at all and expect the user to use the driver equivalent ones
(-shared for example). This would match gcc's behavior, no?
