  gstreamer fails with "cannot allocate memory in static TLS block"
  error on aarch64

Bug description:
  [Impact]

  gstreamer cannot load some plugins on 20.04, aarch64 due to TLS memory
  exhaustion, so these plugins cannot be used. See LP#1846837 and
  LP#1914030.

  This is solved apparently on glibc 2.32:
  https://sourceware.org/bugzilla/show_bug.cgi?id=25051
  by patch
  https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=ffb17e7ba3a5ba9632cee97330b325072fbe41dd

  [Test Case]

  Running totem-video-thumbnailer shows these errors:

  (totem-video-thumbnailer:12136): GStreamer-WARNING **: 00:43:52.740:
  Failed to load plugin '/usr/lib/aarch64-linux-
  gnu/gstreamer-1.0/libgstlibav.so': /lib/aarch64-linux-
  gnu/libgomp.so.1: cannot allocate memory in static TLS block

  [Where problems could occur]

  This is delicate code in glibc with quite regression potential. Said
  this, the code is in the next minor release (2.32, while focal has
  2.31), which has been running groovy for a while.

  Also, apparently there is a 2.31 patch for groovy, before it moved to
  2.32: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964141
