Title:
  oss4 does not build on ppc64el on groovy

Status in binutils package in Ubuntu:
  Invalid
Status in oss4 package in Ubuntu:
  In Progress

Bug description:
  When building the focal version of oss4 with groovy version of
  binutils, it fails with:

  /tmp/ccoZchTf.s: Assembler messages:
  /tmp/ccoZchTf.s: Error: invalid attempt to declare external version name as default in symbol `.snd_pcm_hw_params_set_rate_near@@ALSA_0.9.0rc4'
  make[1]: *** [Makefile:16: pcm.lo] Error 1

  Downgrading binutils to 2.34-6ubuntu1 fixes the problem. This works
  with gcc-9 9.3.0-10ubuntu2. Upgrading to groovy gcc-9 9.3.0-17ubuntu1
  will force the upgrade of binutils, so can't be tested with the
  working version of binutils. Using the latest version of gcc-9 or
  gcc-10 from groovy with the broken binutils is still broken, so a
  complete upgrade does not fix the problem.

  The following diff does fix the problem with binutils 2.35-2ubuntu1, though:
