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.

would now like to get a 64-bit assembler from GNU. Is there one
available? If not yet, when might it appear? Of course I
also want a new C compiler to take advantage of the processor. Again, is
there one yet?

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
if you want a different toolchain than the one provided by the OS.

Or you can build one from source.
