Bug description:
  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.
