That's supported but not in the most elegant fashion.
In your Makefile in the top-level directory
just specify the relevant .o files in the subdirectories.
So you would have:
lguest-y := file.o
lguest-y += dir/foo.o
lguest-y += dir2/bar.o

obj-$(CONFIG_...) := lguset.o

If you have trouble making this work drop me a mail and I
will try to help with a more specific example.
