I'm not sure. For starters, the Aarch64 builders have kinda been
forgotten since Yao stopped contributing regularly to GDB (he is the
maintainer of the machines behind the builders). So the very first
thing we'd need to do is to put the builders in a good shape again
(they're currently with 273 pending builds in the queue!). This is
something that's been on my TODO list for a while now, and I was going
to ask Alan (or anyone from ARM) if they're not interested in taking
over the maintenance of these machines.

Then, I think the best approach for the SVE builds would be to manually
download a Linux kernel, put the sources somewhere, and then I could
configure a specific builder to build GDB with the SVE headers.
