Why are CONFIG_LOCKDEP_SUPPORT, CONFIG_TRACE_IRQFLAGS_SUPPORT, and CONFIG_STACKTRACE_SUPPORT not defined for PowerPC?

[Timur Tabi]

These three Kconfig options:

	CONFIG_LOCKDEP_SUPPORT
	CONFIG_TRACE_IRQFLAGS_SUPPORT
	CONFIG_STACKTRACE_SUPPORT

Are not defined for ppc or powerpc, but they are defined for several other 
architectures.  I'm trying to debug some semaphore locks in ALSA, and these 
defines are necessary to enable some other Kconfig features.
