tracing: Fix TRACING_SUPPORT dependency for PPC32
commit 40ada30f9621fbd831ac2437b9a2a399aa ("tracing: clean up menu"), despite the "clean up" in its purpose, introduced a behavioural change for Kconfig symbols: we no longer able to select tracing support on PPC32 (because IRQFLAGS_SUPPORT isn't yet implemented). The IRQFLAGS_SUPPORT is not mandatory for most tracers, tracing core has a special case for platforms w/o irqflags (which, by the way, has become useless as of the commit above). Though according to Ingo Molnar, there was periodic build failures on weird, unmaintained architectures that had no irqflags-tracing support and hence didn't know the raw_irqs_save/restore primitives. Thus we'd better not enable irqflags-less tracing for all architectures. This patch restores the old behaviour for PPC32, and thus brings the tracing back. Other architectures can either add themselves to the exception list or (better) implement TRACE_IRQFLAGS_SUPPORT.
