[Bug 2100274] [NEW] ld.so from glibc 2.41 drops symbol __nptl_change_stack_perm@@GLIBC_PRIVATE

Public bug reported:

This has the following consequences:

* Breaks fakechroot when chrooting into a system with an older libc
  -> Honestly not too much of a problem for me, the approach was very fragile
* Renders the system *completely* unusable if the ld.so has been upgraded but not the libc, e.g. in case of power loss while unpacking libc6.deb
  -> More problematic

** Affects: fakechroot (Ubuntu)
     Importance: Undecided
         Status: New

** Affects: glibc (Ubuntu)
     Importance: High
         Status: In Progress


** Tags: update-excuse

** Also affects: fakechroot (Ubuntu)
   Importance: Undecided
       Status: New
