Indeed, this works fine with the 'make' on FreeBSD, NetBSD, OpenBSD,
Solaris 10, and AIX.

Looks fine.

Except possibly that POSIX does not allow this? Then we would need a
pseudo-target the turns off only the non-standardized part of the built-in
database, say, .NO_GNU_BUILTINS. And users would have to write:

  .SUFFIXES:
  .NO_GNU_BUILTINS:
