Many packages, including GCC, install Python files for GDB in library
diretory. ldconfig reads them and issue errors since they aren't ELF
files:

ldconfig: /usr/gcc-5.1.1/lib/libstdc++.so.6.0.21-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

ldconfig: /usr/gcc-5.1.1/libx32/libstdc++.so.6.0.21-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

ldconfig: /usr/gcc-5.1.1/lib64/libstdc++.so.6.0.21-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

This patch silences ldconfig on GDB Python files by checking filenames
with -gdb.py suffix.

	[BZ #18585]
	* elf/readlib.c (is_gdb_python_file): New.
	(process_file): Don't issue errors on filenames with -gdb.py
	suffix.
