Tcl has {*} expanding a list to be treated as arguments. Empty elements
disappear. Thinking about it some more, yes that behaves as intended and is
relatively easy to read and write:
exec gcc {*}$cppflags {*}$cflags -o $@ $<
So we can cross out Tcl from the list of languages that benefit from such
change.
