This syntax isn't supported by GNU make.

I think the documentation is pretty clear on this. Try looking, for
example, at the chapter "Incompatibilities and Missing Features", where
this is explicitly mentioned along with a workaround using GNU make
syntax which may or may not meet your needs (it covers much but not all
of the potential uses for this syntax).
uh> 1. Shall GNU make support the same features?
Do you mean, will it in the future? I'm not sure. There is a patch
around which implements some of the Sun syntax. I'm not sure it'll do
what you want above ($$ variable reference inside another $$ variable
reference). I haven't examined the patch myself.
Personally, I think this syntax is unclean and a bad way to implement
the functionality you want. I'm hoping to implement a more generic
feature which will allow this type of behavior, plus more, in the
future.
uh> 2. If not, is there a way workaround this?
See the manual.
You can do the things that static pattern rules don't allow by using
automatically generated makefiles, although this is slightly more
complicated.
