devel/smake: Update to 1.3nb14

New features with AN-2020-09-04:
- autoconf: congig.guess: FreeBSD on 64 bit ARM returns arm64 from
  uname -m; this was previously not supported and rejected by config.sub.
  We now convert "arm64" into "aarch64" in config.guess to get the usual
  expected results.

- Makefile system: RULES/rules.env The environment variables FIGNORE,
  LD_LIBRARY_PATH LD_LIBRARY_PATH_32 and LD_LIBRARY_PATH_64 are now
  unexported from the enviroment.

  In special FIGNORE is dangerous, as it is frequently used by bash
  users but tells ksh93 to modify it's behavior with "echo *" and
  this may cause strange things with our makefiles in case that
  /bin/sh is ksh92. This applies e.g. to Oracle Solaris 11 and
  OpenSolaris.

- smake: new version date, this had been forgotten with the last change

New features with AN-2020-10-09:
- autoconf: Added support for newer HP-UX versions on Itanium.

  Thanks to Rudi Blom for reporting and making a change proposal.
