  qemu-user can't run some ppc binaries

Status in QEMU:

Bug description:
  qemu-user v6.0.0-rc5, built in static mode, will crash for certain ppc
  binaries.  It seems to have something to do with glibc for some Centos
  versions.  The problem is easiest to see with statically-linked

  The attached Dockerfile shows how to produce a ppc binary that will
  crash qemu-user.  Here is how to reproduce the problem:

  $ uname -m

  $ docker run --rm --privileged multiarch/qemu-user-static --reset -p

  $ docker build -t qemu-bug:centos -f Dockerfile.centos .

  $ docker run --rm -it -v$PWD:$PWD -w$PWD qemu-bug:centos cp
  /helloworld-centos.static.ppc .

  $ qemu-ppc-static --version
  qemu-ppc version 5.2.95 (v6.0.0-rc5)

  $ qemu-ppc-static ./helloworld-centos.static.ppc
  emu: uncaught target signal 4 (Illegal instruction) - core dumped
  [1]    16678 illegal hardware instruction (core dumped)  qemu-ppc-static
