The issue is gdb not yet upstream.

Right - that works around gdb, but gcc upstream still has partial support for ARCv2 with patches being reviewed very sloooowly by the old ARC port maintainer. You could give it a try though ! > Should arc-*-* list gdb in their noconfigdirs like many other archs do > too? Yeah indeed that chould be done while gdb upstream is waiting. @Anton can we do that - update binutils/configure.ac to not configure gdb for ARC.
