I general I am fine with factoring the selftest code out to a separate
module.  However there are two problems:

The minor one is that selftest_help.c has an underscore in the name,
which should be replaced by a dash.  For easier grepping the source tree
I also suggest to use a different name; for example "cipher-selftest.c"

The other problem is that code like

  static char error_str[128];
  snprintf (error_str, sizeof(error_str),
            "%s-128-CBC test failed (plaintext mismatch)", cipher);
  return error_str;

is not thread-safe and should not be done this way.  To avoid the
overhead of adding static memory management code, what about this:

  syslog (LOG_USER|LOG_WARNING, "Libgcrypt warning: "
          "%s-128-CBC test failed (plaintext mismatch)", cipher)
#endif /*HAVE_SYSLOG*/
  return "selftest for 128 bit CBC failed - see syslog for details";



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
