[Bug tapsets/10206] symname() resolves incorrect symbols on ppc

The typical case when this lookup fails is when trying to decode what the
function pointer passed to a notifier is. For the current case, we were getting
addresses corresponding to the 'd' (NOTYPE) symbols below:

[root@llm27lp1 ~]# nm --format=sysv /boot/vmlinux-2.6.30-rc7 |grep migration_call
