You're out of luck except for eBay. Amazon was the only one that might have done it, but they don't accept PayPal for purchases. Either transfer the funds to an actual account, or find something else to spend the money on.
What you can do though is prowl eBay looking for the gift cards. You may have to pay a slightly marked up price, but just be sure to contact the seller (if you buy it) with a request just for the code. At that point, it is just trust in the seller.
Be aware, if you're looking for a $5 gift card or something, good luck. Most only sell the slightly higher priced ones.
Edit: To the person below - He already said he didn't want a physical iTunes card, so why would he wait for a PayPal debit card so that he could wait for it to ship, then use it to order an iTunes card that he was to wait for it to ship?
