*-linux-nat: Handle null inferior in read_description.
Don't invoke ptrace in the target read_description method if there is not an active inferior to query via ptrace. Instead, use the default register set for the architecture. Previously the native target could report an error from a failed ptrace operation when fetching a tdesc without an attached process. For example on Linux x86-64: (gdb) target native Done. Use the "run" command to start a process. (gdb) unset tdesc filename Couldn't get CS register: No such process.
