We discussed this problem recently at Parse C-like define statements. Using a variation on the solution presented by danger and sfink: 
# after your first foreach loop
foreach my $key (keys %var) {
   1 while $var{$key} =~ s/([a-z_]+)/$var{$1}/;
   $var{$key} = eval "$var{$key}";
}

should do the trick.

On another note - i would remove the first line in your first foreach loop (the one with the tr) and change the last line of that loop to: 

$var{$key} = "\L$value\E";

UPDATE - or maybe not :) - i overlooked the fact that the first few lines of the output have uppercase keys - my mistake.
