Hi Maurizio, glad to see you ask these questions! For those who read this later but aren't involved in Maurizio's/mine email exchange: you get the SDK under [1] in its current version, installation instructions under[2].
So, you're right. With the E310, you'll need to use a cross-compiler to generate binaries for the E310; you can also do "small" compilations on the device itself, but we generally try to encourage people not to do that -- building something as big as whole GNU Radio would take overly long on the embedded processor of the E310. So, two aspects: If your flow graph doesn't use graphical sinks (ie. it works in the "no gui" build option), and only uses the blocks that GNU Radio comes with, you can just copy over the resulting python file to your E310 (e.g. via SCP), and run it there, unmodified. Especially if you already have experience with the B210, this is handy: Anything that works with the B210, and for which the E310's CPU is fast enough, should also work on the E310 (with very little restrictions). So you can design and test your flow graphs on your PC with the B210, and if they work and are fairly optimized, just copy them over to the E310. Now, if you need custom GNU Radio modules, and you need to build C++ GNU Radio blocks, you'll actually need to cross compile. [2] has a paragraph on building GNU Radio; do that, and also do the same (adjusting the path to the platform cmake file) with your OOTs, and you should be fine.
