    Rename _doprnt -> _bfd_doprnt to fix DJGPP bfd build (and likely others)
    
    Building bfd/ for DJGPP, I see:
    
     ../../src/bfd/bfd.c:642:1: error: conflicting types for '_doprnt'
      _doprnt (FILE *stream, const char *format, va_list ap)
      ^~~~~~~
     In file included from ../../src/bfd/sysdep.h:37:0,
    		  from ../../src/bfd/bfd.c:367:
     /usr/lib64/gcc/i586-pc-msdosdjgpp/6.1.0/include-fixed/stdio.h:171:5: note: previous declaration of '_doprnt' was here
      int _doprnt(const char *_fmt, va_list _args, FILE *_f);
          ^~~~~~~
    
    Possible fixes the build on other systems too -- _doprnt was/is an
    exported symbol on old Unix/BSD systems too.
    
    bfd/ChangeLog:
    2017-10-11  Pedro Alves  <palves@redhat.com>
    
    	* bfd.c (_doprnt): Rename to ...
    	(_bfd_doprnt): ... this.
    	(error_handler_internal): Adjust.
    
    (cherry picked from commit 8f314ad58ec824ce6c8467af29f11583f79a80ea)
