To be honest, I don't see the point of adding this.  Take a look at
what your change does:

OK... there is a much easier way.

drow@nevyn:~% echo $DEJAGNU
/home/drow/.dejagnu/site.exp
drow@nevyn:~% cat >> $DEJAGNU <<EOF
if { "$tool" == "gdb" } {
  lappend ignoredirs gdb.cp
}
EOF

$target_alias is there too.  Even $srcdir should be available by this
point, giving you great freedom.
