iirc it tells add on packages where they should install.

TCL_PACKAGE_PATH is the value with which the tcl-variable
tcl_pkgPath gets initialized at startup of the interpreter.
The tcl interpreter searches required packages under this
path.

Add on packages (like e.g. tcl-readline) check the tclCOnfig.sh,
and install under this path so the interpreter finds them.

I think initially it is just prefix/lib. Now with TCL_PACKAGE_PATH as prefix/lib,
user-installed tcl-packages would be hinted by their configure system to install
in a subdirectory of prefix/lib, in our case /usr/pkg/lib.
And we don't want tcl packages to be in /usr/pkg/lib but in /usr/pkg/lib/tcl I guess.
