I don't think so:
libcacard.la: $(libcacard-lobj-y)
        $(call LINK,$^)

The problem is the libcacard-obj-y target is not required by anything.

Try this on qemu.git/master:

$ make distclean
$ ./configure
$ make libcacard/vscclient
libcacard/vscclient.o: In function `do_command':
/home/stefanha/qemu/libcacard/vscclient.c:500: undefined reference to
`vreader_get_reader_by_id'
/home/stefanha/qemu/libcacard/vscclient.c:502: undefined reference to
`vcard_emul_force_card_insert'
/home/stefanha/qemu/libcacard/vscclient.c:503: undefined reference to
`vreader_get_name'
...

The Makefile is broken.  I suspect that putting proper dependencies in
place with fix this issue.
