[resend with libc-alpha]
Hi Adhemerval,

Your recent commit 4af6982e4c9fc465ffb7a54b794aaaa134241f05 ("elf: Fix
elf_get_dynamic_info definition")  causes a lot (but not all) of my
applications
to segfault:

Program received signal SIGSEGV, Segmentation fault.
_dl_fixup (l=<optimized out>, reloc_arg=<optimized out>) at dl-runtime.c:146
146       return elf_machine_fixup_plt (l, result, refsym, sym, reloc,
rel_addr, value);
(gdb) bt
#0  _dl_fixup (l=<optimized out>, reloc_arg=<optimized out>) at dl-runtime.c:146
#1  0x00007ffff7fe251a in _dl_runtime_resolve_xsavec () at
../sysdeps/x86_64/dl-trampoline.h:126
#2  0x000055555555634e in main (argc=1, argv=0x7fffffffd568) at
iconvconfig.c:288

Reverting the commit fixes the problem. Gcc, python, etc seem to be
not affected, while for example iconvconfig and openssh are.

Thanks,
    Manuel
