I think the issue is the file command, using a more recent one it does show
that ldconfig is a static-pie:

$ file elf/ldconfig
elf/ldconfig: ELF 64-bit LSB pie executable, x86-64, version 1 (GNU/Linux), 
static-pie linked, for GNU/Linux 3.2.0, with debug_info, not stripped

$ readelf -l elf/ldconfig  | grep INTERP
$
