Fix dynamic linker issue with bind-now
Fix the bind-now case when DT_REL and DT_JMPREL sections are separate
and there is a gap between them.
[BZ #14341]
* elf/dynamic-link.h (elf_machine_lazy_rel): Properly handle the
case when there is a gap between DT_REL and DT_JMPREL sections.
* sysdeps/x86_64/Makefile (tests): Add tst-split-dynreloc.
(LDFLAGS-tst-split-dynreloc): New.
(tst-split-dynreloc-ENV): Likewise.
* sysdeps/x86_64/tst-split-dynreloc.c: New file.
* sysdeps/x86_64/tst-split-dynreloc.lds: Likewise.
