[Bug 2000239] [NEW] Segfault by ldconfig.real in Ubuntu for Xilinx

[Timo Schlüßler]

Public bug reported:

When trying to install any additional package to the 'Sysroot for cross-
compilation' (https://people.canonical.com/~platform/images/xilinx/kria-
ubuntu-22.04/iot-limerick-kria-classic-
desktop-2204-x06-20220614-78-sysroot.tar.xz?_ga=2.175093282.1232585684.1671609425-2015364329.1671609425,
linked at https://ubuntu.com/download/amd-xilinx) I get a segmentation
fault caused by ldconfig called by libc-bin.postinst:

```
Setting up libc-bin (2.35-0ubuntu3.1) ...
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault
dpkg: error processing package libc-bin (--configure):
 installed libc-bin package post-installation script subprocess returned error exit status 139
Errors were encountered while processing:
 libc-bin
```

Downgrading libc-bin to version 2.31 fixes this issue. 2.35 and 2.36
both equally result in the segfault.

The host system is:
Description:    Debian GNU/Linux 10 (buster)
Release:        10
running on Windows Subsystem Linux.

** Affects: glibc (Ubuntu)
