Except that it ships with a 32-bit/armv7 kernel and user space, and you 
can't run 64-bit/armv8 code on a 32-bit/armv7 kernel.  It isn't clear 
when or if a 64-bit kernel will be available.  When/If they provide a 
64-bit kernel and user space, then it will come with a 64-bit armv8 
compiler.

The Odroid C2 has a 64-bit kernel, but is apparently not stable yet. 
This is about 40 USD.

There are 64-bit boards available from www.96boards.org that come with a 
reasonably stable 64-bit kernel and user space, including a compiler. 
These start at about 100 USD.

If you have access to an x86 Ubuntu machine, then "apt install 
gcc-aarch64-linux-gnu" will work to get a cross toolchain to aarch64.

Linaro has minimally supported cross toolchain binaries for x86 Ubuntu 
available at
    http://releases.linaro.org/components/toolchain/binaries/
if you want a different toolchain than the one provided by the OS.

Or you can build one from source.
