"Availability" doesn't mean much. There are plenty of all kinds of libs available on all platforms (who wants to program WiFi access for the embedded sensor from scratch, for example?). Doesn't mean it makes sense to put any of them into the current project. The stdlib is one of many and not that often the one that is put in. The libs I use on my embedded system are much more likely to be for some specific piece of sensor or I/O device (like the mentioned WiFi module), I rarely have need for what's in the stdlib. Of course, embedded systems vary far more than the PC and server stuff so you can easily find people who will say the exact opposite.
