make localmodconfig doesn't work for thunderbolt

Hi,

if I use localmodconfig for example like this:
mkdir /tmp/tb/
echo thunderbolt >/tmp/tb/lsmod
make O=/tmp/tb LSMOD=/tmp/tb/lsmod localmodconfig

I get:
using config: '.config'
thunderbolt config not found!!

$ grep 'USB4\>' /tmp/tb/.config
# CONFIG_USB4 is not set

I believe it's due to:
  obj-${CONFIG_USB4} := thunderbolt.o
in drivers/thunderbolt/Makefile. I.e. ${} used instead of more common $().

But even if I change the parser:

--- a/scripts/kconfig/streamline_config.pl
+++ b/scripts/kconfig/streamline_config.pl
@@ -317,7 +317,7 @@ foreach my $makefile (@makefiles) {
        $_ = convert_vars($_, %make_vars);

        # collect objects after obj-$(CONFIG_FOO_BAR)
-       if (/obj-\$\((CONFIG_[^\)]*)\)\s*[+:]?=\s*(.*)/) {
+       if (/obj-\$[({](CONFIG_[^})]*)[)}]\s*[+:]?=\s*(.*)/) {
            $var = $1;
            $objs = $2;


I see:
module thunderbolt did not have configs CONFIG_USB4

and:
$ grep 'USB4\>' /tmp/tb/.config
# CONFIG_USB4 is not set

So two questions:
1) is ${} supported and should be the above change sent as a patch? Or should be drivers/thunderbolt/Makefile fixed to use $(). (And maybe other Makefiles too.)

2) how to fix that 'thunderbolt did not have configs'?

thanks,
