perf: Always build the powerpc perf_arch_fetch_caller_regs version 

Now that software events use perf_arch_fetch_caller_regs() too, we
need the powerpc version to be always built.

Fixes the following build error:

	(.text+0x3210): undefined reference to `perf_arch_fetch_caller_regs'
	(.text+0x3324): undefined reference to `perf_arch_fetch_caller_regs'
	(.text+0x33bc): undefined reference to `perf_arch_fetch_caller_regs'
	(.text+0x33ec): undefined reference to `perf_arch_fetch_caller_regs'
	(.text+0xd4a0): undefined reference to `perf_arch_fetch_caller_regs'
	arch/powerpc/kernel/built-in.o:(.text+0xd528): more undefined references to `perf_arch_fetch_caller_regs' follow
	make[1]: *** [.tmp_vmlinux1] Error 1
	make: *** [sub-make] Error 2
