They’re showcasing their open-source stack, built on existing tools, for their own FPGA.
Imagine if, 25 years ago, a company had designed a new CPU ISA and core and, as part of the development process, ported GCC and done a nice job
tuning the existing optimization passes, with the intention of the GCC port being the primary toolchain that commercial users would use. They could write a blog post about it, and it would have been great. Maybe they even would have acknowledged in the blog post that the stack included binutils :)
in that case, such a company would be wise to include the fact that the "z1060" is a new CPU instead of failing to even mention what it is in their "new GCC port" press release page
