Why is _dl_relocate_static_pie linked into crt1.o?

[Florian Weimer]

I see this:

“
$ objdump -d --reloc /usr/lib64/crt1.o

/usr/lib64/crt1.o:     file format elf64-x86-64


Disassembly of section .text:

0000000000000000 <_start>:
    0:   31 ed                   xor    %ebp,%ebp
    2:   49 89 d1                mov    %rdx,%r9
    5:   5e                      pop    %rsi
    6:   48 89 e2                mov    %rsp,%rdx
    9:   48 83 e4 f0             and    $0xfffffffffffffff0,%rsp
…

0000000000000030 <_dl_relocate_static_pie>:
   30:   c3                      retq
”

Isn't _dl_relocate_static_pie useless there?  It will not be used in 
dynamically linked binaries.  Should it be included in libc_nonshared.a 
instead, so that static PIE binaries pick it up, as needed?

Thanks,
