      The ld.so CPU diagnostics are currently broken because the POWER9 memset is used before the POWER9 compatibility check. This result in an ld.so crash instead of proper error message.

      Fixed upstream via:

      commit f6ea5d1291cf3f264514d03872ebae84e0293b69

    Linux: Include <dl-symbol-redir-ifunc.h> in dl-sysdep.c
    
    The _dl_sysdep_parse_arguments function contains initalization
    of a large on-stack variable:
    
      dl_parse_auxv_t auxv_values = { 0, };
    
    This uses a non-inline version of memset on powerpc64le-linux-gnu,
    so it must use the baseline memset.
