As your research has revealed, you are using an outdated b2 version instead
of the one that is included in the distribution. The one in the
distribution says:

===
$ ./b2 -v
B2 Version 4.2. OS=LINUX.
  Copyright 1993-2002 Christopher Seiwald and Perforce Software, Inc.
  Copyright 2001 David Turner.
  Copyright 2001-2004 David Abrahams.
  Copyright 2002-2019 Rene Rivera.
