Allow IFUNC relocation against unrelocated shared library
IFUNC relocation against definition in unrelocated shared library
will lead to segfault when the IFUNC function is called.  This
patch allows such IFUNC relocations with a warning.  This isn't
a real fix for

https://sourceware.org/bugzilla/show_bug.cgi?id=21041

It simply allows the program to load.  The program will segfault
when longjmp is called.

	* sysdeps/i386/dl-machine.h (elf_machine_rel): Replace
	_dl_fatal_printf with _dl_error_printf for IFUNC relocation
	against unrelocated shared library.
	* sysdeps/x86_64/dl-machine.h (elf_machine_rela): Likewise.
