Comment (by kencu):

 Yeah, I don't think it ever worked, indeed.

 for the short term, we should mark the appropriate systems as having no
 universal variant.

 for the medium term, someone might build it like gcc10-bootstrap, and then
 it will be at least sorta universal

 for the longer term, the plan would be a fully universal gccN+ with
 libraries that support arm64/x86_64 and fully universal cross compilers
 (ie the arm64 and x86_64 compilers both exist universal in both arches).

 for the long long term, someone will fix driverdriver.c to make it all
 work as seamlessly as clang and apple-gcc42 work, supporting multiple arch
 flags.
