Hm, interesting. After following the directions above and setting
CONFIG_LD_HEAD_STUB_CATCH=y and then rebuilding, the "should be" address
has changed:

ERROR: start_text address is c000000000000500, should be c000000000000200
ERROR: try to enable LD_HEAD_STUB_CATCH config option
ERROR: see comments in arch/powerpc/tools/head_check.sh
