In theory yes - in practice I don't know if anyone has tried it. How 
would you do a native build using the ARM64 sources rather than the 
aarch64 sources?

My point was more that this is still not really clear. You now have a 
section that indicates you can do a native build on Aarch64, but then 
within the Cross-compilation section you have "Building for ARM/aarch64" 
which suggests to me that 64-bit is only done using cross-compilation. 
And the two different ports are only mentioned within that 
cross-compilation section.
