* add --enable-smartcard and --disable-smartcard flags
 * let the nss check only disable building the ccid-card-emulated device
 * report only if nss is found or not, not smartcard build inclusion
 * don't link with NSS if --disable-smartcard-nss

The --disable-smartcard flag really should go with the initial smartcard
changes to configure. That way it is possible to test that each
individual patch doesn't break the build when smartcard support is
enabled or disabled. If you add it at the end, you figuring out which
patch is the problem is much harder.

Adding the smartcard-nss flag should go next to the patch that adds the
code relying on the flag.

Cheers,
Jes
