I think extra_options ought to be a one-level list, i.e.
{key1 value key2 value2 ...}.  That makes the calls simpler
(because there's one fewer [list ...]) and:

reduces to:

    foreach { opt_name opt_val } $extra_options {
	if ![info exists opts($opt_name)] {
	    perror "unknown option $opt_name given in extra_opts"
	    unresolved $subdir/$name
	    return
	}
	# Add extra option to end of existing option, adding space
	# if necessary.
	if { ![regexp "warning|error" $opt_name]
	     && [string length $opts($opt_name)] } {
	    append opts($opt_name) " "
	}
	append opts($opt_name) $opt_val
    }

OK with that change, thanks.  OK for the follow-up too.
