If you plan to run Linux there I see no reason why you could not use the 
native ARM compiler for evaluation. A cross compiler would change little 
or nothing in that case.

We are using a cross compiler for our custom target boards because it 
can be hosted on a powerful x86 machine instead of a sluggish ARM which 
also tend to crash under load or freeze when it goes into the swap.

Otherwise, nothing changes. We can perfectly well compile everything 
using GNAT FSF on an ODROID-XU4. It would only take a week instead of a 
day to build...
