Debian distribution includes two versions of Tcl package (tcl8.3 and
tcl8.4), the third, tcl8.5, will be packaged in near future. Their
development libraries may be installed simultaneously. And if we allow
to find tclConfig.sh using your patch we'll get undefined behavior,
where you'll never know in advance which Tcl library will be linked to
your application or extension.

I think that the current approach (using --with-tcl and
--with-tcl-includes) is more robust.
