[Patch] fix default --prefix in tix install

[Patch] fix default --prefix in tix install

[Mo DeJong]

Hello all.

A problem in TIX shows up when the user does not pass a --prefix option to
the toplevel configure. This patch fixes the error, the approach was swiped
from the Tcl and Tk configure.in scripts.

2002-07-02  Mo DeJong  <supermo@bayarea.net>

	* unix/tk8.3/configure.in: Default the prefix and
	exec_prefix to /usr/local if the user does not
	pass --prefix explicitly. This avoids an error
	during make install where the TCL_BIN_DIR
	variable is set to NONE/bin.
