Make desktutils/ical building again.

This was a tricky thing and I suspect this is caused by the new
tcl83 package rolled out. What happens is that lib/tcl8.3/tclConfig.sh
has this line in it:
	TCL_LIB_FILE='libtcl83${TCL_DBGX}.so.1'
The single ticks TCL_DBGX not to be expanded, that's okay. But the
configure-script didn't evaluate the variable once it got it from
the tclConfig.sh script.
