So I understand Alan Modra already checked in a change to shlib-versions to
set the minimum symbol version for powerpc64le.  If we only use ELFv2 with
powerpc64le, is there anything else that needs to be done?

As to the configure check, I guess we could add something along these lines
to the configure.ac file I added:

# We support only the ELFv1 ABI on big-endian powerpc64-linux,
# and only the ELFv2 ABI on little-endian powerpc64le-linux.
if test -z "$enable_hacker_mode"; then
  if test "$config_machine" = powerpc64le; then
    if test $libc_cv_ppc64_elfv2_abi = no; then
      AC_MSG_ERROR([Only the ELFv2 ABI is supported on powerpc64le-linux.])
    fi
  else
    if test $libc_cv_ppc64_elfv2_abi = yes; then
      AC_MSG_ERROR([Only the ELFv1 ABI is supported on powerpc64-linux.])
    fi
  fi
fi

Is this what you were thinking about?

Bye,
