Check IFUNC definition in unrelocated shared library [BZ #20019]
Calling an IFUNC function defined in unrelocated shared library may
lead to segfault. This patch issues an error message to request
relinking the shared library if it references IFUNC function defined
in the unrelocated shared library.
[BZ #20019]
* sysdeps/i386/dl-machine.h (elf_machine_rel): Check IFUNC
definition in unrelocated shared library.
* sysdeps/x86_64/dl-machine.h (elf_machine_rela): Likewise.
