Overview
Comment:After autosetup checks for the existence of tclsh in the PATH, it now checks whether it's at least version 8.6, because macOS is still shipping 8.5, despite it being nearly 6 years old. If we find an old tclsh, try to find the Homebrew tcl-tk package, and use that version instead. This is not a macOS or Homebrew specific change in principle: we can extend this logic for other systems to find their best Tcl/Tk version, as needed.

On systems where autosetup is used, this only affects "make test". There are other uses of tclsh in this tree which may also benefit from our PATH discoveries, but this checkin doesn't update those.

This checkin also doesn't try to address similar problems on other platforms, such as the "TCLSH = tclsh" line in Makefile.mingw.

Explained "Why can't we use Jim Tcl for the test suite?" in the auto.def comment above the check for a suitable tclsh version. Basically, I tried it and then documented a few of the resulting failures. check-in: 91eaef61 user: wyoung tags: tclsh-macos
