I configured it with (build, target, host = ppc) and it hit this error.

I don't see how get_memory_ranges() from kexec-ppc.c could ever work.
Maybe it should not even compile.

from kexec-ppc.c

/* Return a sorted list of memory ranges. */
int get_memory_ranges(struct memory_range **range, int *ranges,
					unsigned long kexec_flags)
{
#ifdef WITH_GAMECUBE
	int memory_ranges = 0;

	/* RAM - lowmem used by DOLs - framebuffer */
	memory_range[memory_ranges].start = 0x00003000;
	memory_range[memory_ranges].end = 0x0174bfff;
	memory_range[memory_ranges].type = RANGE_RAM;
	memory_ranges++;
	*range = memory_range;
	*ranges = memory_ranges;
	return 0;
#else
	fprintf(stderr, "%s(): Unsupported platform\n", __func__);
	return -1;
#endif
}

I guess I should check with configure options kexec-tool.ppc uses, to see if there is a change it
could ever work.

I had already reported it
