An editorial on this subject was requested by arnej who reminded me on GamingOnLinux's IRC channel that there is now another, perhaps even more important reason not to buy games in advance of their actual release on Linux.
Makes sense. With Feral and Aspyr having crossed over into the frontiers of Linux gaming with XCOM: Enemy Unknown and Civilization 5 respectively, plus all their downloadable content and both massive titles in terms of gameplay, brand, budget, and so on, it stands to reason that such endeavours should be rewarded, especially when both titles aren't brand new and thus pose more of a risk for the both of them.
Here's what Aspyr_Blair said on the matter:

Buying a game that does not yet have a Linux client doesn't make sense anyway since you cannot play the game. Apart from that, it is always wise to wait and see how good of a port it actually is. Don't spend your money blindly!
arnejThe contracts of Feral and Aspyr will only get paid for purchases after a port happened. We now have another reason to only buy games when they are available for Linux: To support the porters.

Aspyr_BlairAspyr gets paid on new or future purchases of the Linux and Mac versions of Civ V. If you purchases the game on Windows say...5 months ago...then the PC publisher/developer was paid for that transaction (as they should be). Essentially, Steam knows what platform you are on through the client and processes payment to the developer accordingly.
Lots of fans are worried that if they purchase through a browser or a PC at work for example, that we wont get compensated. As long as you play the game on your Linux or Mac in the first week or so and stay on that platform for your play, the payment will then shift over to us as the Linux publisher/developer.

Aspyr_BlairDLC's are treated as separate transactions, so if you purchase BNW today on your Linux client, we will get the credit.

Aspyr_BlairWe are paid only for Mac/Linux purchases.
The key is the target system should be played on in the first week or two, otherwise the sale defaults to the primary platform (in this case, PC). Still...Valve has some metrics on handling weird cases like that and we do get compensated. Example: mobile browser purchased but not launched on Linux until 5 weeks later...etc.
If you want to be SURE, launch the game on the target system relatively quickly, even if you dont play it much, that launch should help the metric.

Aspyr_BlairAs long as you purchased the gift version through your Linux Steam client, we should be golden. Just also make sure that whomever you gift it to is playing on Linux or Mac ;)

Aspyr_BlairIf you purchase on the Linux client, Aspyr would get credit for the sale immediately BUT Steam is smart, so once your buddy plays on Windows the system knows that user is really a PC customer and gives the credit back over to the fine folks at 2K. Sometimes there is a grey area where we split the revenue up but that is pretty rare. Its really a pretty smart system.

icculusInstall and play it on Linux for the first week after you buy it and they consider it a Linux sale.

Some you may have missed, popular articles from the last month:
This system doesn't sound very fair to me. Often enough I buy games because they have Linux support, but I end up streaming them from Windows to my HTPC. Unfortunately Linux can not be used as a host OS for Valve's In-Home Streaming, yet.
XCom would be such a candidate. I'd rather prefer playing it with a controller in front of a large TV screen. But knowing this now, I will resist :-)
A game that was bought with a Linux system should always count as a Linux game, no matter on which platform you play it.
