All libcacard actually needs are the NSS libs. Linking against the entire
world is a regression caused by

  commit 9d171bd937
  Author: Michael Tokarev <mjt@tls.msk.ru>
  Date:   Thu May 8 16:48:27 2014 +0400

    libcacard: remove libcacard-specific CFLAGS and LIBS from global vars

Which removed the setting of the LIBS variable in libcacard/Makefile.

Adding it back as an empty assignment brings the linked libs back to a more
reasonable set
