relocation: Do not relocate NULL pointers.
NULL is an absolute value and should not be relocated. After this correction code like: void weak_fun(void) __attribute__((weak)); printf("weak_fun:%p\n", weak_fun); will still print null after relocation. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
