[Bug 2100297] [NEW] dlopen(libx264/libde265) fails on armhf with glibc 2.41

[Simon Chopin]

Public bug reported:

Due to the changes in GNU_STACK exec flag handling in 2.41, it is now
not possible to dlopen a shared library that requires an executable
stack.

Both x264 and libde265 produce such objects, simply because some of
their objects files for ARM are produced from assembly code that lack
any definition for the GNU_STACK ELF field, and for retrocompatibility
the tooling will default to an executable stack.

Both libs should be fixed, and glibc should probably declare some Breaks
on them.

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