Subject: tracing, alpha: undefined reference to `save_stack_trace'

tracing, alpha: undefined reference to `save_stack_trace'

Impact: build fix on !stacktrace architectures

only select STACKTRACE on architectures that have STACKTRACE_SUPPORT

... since we also need to ifdef out the guts of ftrace_trace_stack().
We also want to disallow setting TRACE_ITER_STACKTRACE in trace_flags
on such configs, but that can wait.
