Our backported patch unconditionally uses assembly instructions for
Power9 and later, which triggers SIGILL on Power8 machines:
| [ 3705.137658] sshd[1703]: illegal instruction (4) at 7fff85526aac nip 7fff85526aac lr 7fff854828e0 code 1 in libcrypto.so.3.0.5[7fff85240000+300000]
Backport upstream's fix for this.
