devel/smake: Update to 1.7nb3

New features with AN-2023-09-28:
- autoconf: Fix machine recognition on POWER9 (ppc64le) systems.
  When buidling schilytools on ppc64le systems, config.sub was
  unable to determine the machine type on some systems.  This also
  broke the version announcement on some of the commands.  Fix this
  error by teaching autoconf about ppc64le.
  Submitted by: Nico Sonack.

- libschily: obey HAVE_LONGDOUBLE, HAVE_FACCESSAT, and
  HAVE_GETDOMAINNAME in libschily-mapvers, fixing the build with
  lld 17 on recent FreeBSD.
