powerpc: do not fixup NULL ptrs
The fixup routine must not fixup NULL pointers. Problem can be seen by char *testfun(void) __attribute__((weak)); char *(*myfun)(void) = testfun; Then add printf("myfun:%p, &myfun:%p\n", myfun, &myfun); before relocation and after relocation. myfun should be NULL in both cases but it is not.
