New Revision: 300116
URL: https://svnweb.freebsd.org/changeset/base/300116

Log:
  Fix build breakage on arm64 by papering over the problem. We implement
  a slightly non-standard %S that's more useful in the UEFI environment,
  so ignore printf errors. There's no good cast to use. We'll need to
  revisit this in the future.
