Cast execl*() NULL sentinels to (char *)
The NULL sentinel argument to the execl*() family of calls must be
cast to (char *), as otherwise:
- platforms where NULL is just 0 (not (void *)) would pass an int
- (admittedly esoteric) platforms where NULL is (void *)0 and (void *)
and (char *) have different memory layouts would pass the wrong kind
of pointer
