* unix/Makefile.in: Subst BUILD_TCLSH and TCL_EXE.

	* unix/configure: Regen.
	* unix/configure.in: Update minimum autoconf version
	to 2.59. Invoke SC_PROG_TCLSH and SC_BUILD_TCLSH.

	* win/configure.in: Update minimum autoconf version
	to 2.59. Invoke SC_BUILD_TCLSH.
	* win/tcl.m4 (SC_PROG_TCLSH, SC_BUILD_TCLSH):
	Split confused search for tclsh on PATH and
	build and install locations into two macros.
	SC_PROG_TCLSH searches just the PATH.
	SC_BUILD_TCLSH determines the name of the tclsh
	executable in the Tcl build directory.
