localtime_r is defined in the same file as localtime, so needs to be weak.
ctime_r is not defined in the same file as ctime, and is not referenced by
the implementations of any standard C functions, so does not need to be
weak. (If it were referenced by a standard C function, the reference
would have to be to __ctime_r and ctime_r would have to be a weak alias of
that.)
