Fix potential ABI change introduced by glibc-rh1398413.patch.

extern void _IO_str_init_static (struct _IO_strfile_ *, char *, int, char *)

     __THROW;

extern void _IO_str_init_readonly (struct _IO_strfile_ *, const char *, int)

     __THROW;

Upstream, this did not have any effect because the function definitions

were prototypes, so there is no upstream fix necessary.

But downstream, we have:

     70 void

     71 _IO_str_init_static (sf, ptr, size, pstart)

     72      _IO_strfile *sf;

     73      char *ptr;

     74      int size;

     75      char *pstart;

     76 {

     77   return _IO_str_init_static_internal (sf, ptr, size < 0 ? -1 : size, pstart);

     78 }

     79 

     80 void

     81 _IO_str_init_readonly (sf, ptr, size)

     82      _IO_strfile *sf;

     83      const char *ptr;

     84      int size;

     85 {

     86   _IO_str_init_static_internal (sf, (char *) ptr, size < 0 ? -1 : size, NULL);

     87   sf->_sbf._f._IO_file_flags |= _IO_NO_WRITES;

     88 }

This results in:

strops.c:71:1: warning: function declaration isn't a prototype [-Wstrict-prototypes]

strops.c:81:1: warning: function declaration isn't a prototype [-Wstrict-prototypes]

It is a potential ABI change, depending on the architecture.  None of

the architectures in Red Hat Enterprise Linux appear to be affected,

though.
