[PATCH 2/3] Do not call fputc from _bfd_doprnt

[Tom Tromey <tom@tromey.com>]

I noticed that _bfd_doprnt can unconditionally call fputc.  However,
when called from error_handler_sprintf, this will likely result in a
crash, as the stream argument does not actually point to a FILE.

	* bfd.c (_bfd_doprnt): Do not call fputc.
