Fixed DESTDIR error.
Import opensc-0.13.0git20140221130957 as wip/opensc.

From TODO:

    (The following is current as of opensc-0.13.0git20140221130957.)

    This is a newer version of security/opensc (a recent snapshot from
    the upstream Git repository).  Only minimal changes to
    opensc-0.12.2 have been made to get it to build; some of the
    contents of the Makefile may no longer be necessary (e.g.,
    CONFIGURE_ARGS, CONFIGURE_ENV, dependencies) and new
    settings/dependencies may be required.  No testing has been done,
    other than to ensure that it builds on NetBSD 6.1 i386.

    TODO:
      * basic testing
      * prune obsolete dependencies and settings from Makefile, if any
      * prune obsolete patches, if any
      * add new dependencies, if any
      * verify that options.mk is still appropriate

From DESCR:

    OpenSC provides a set of libraries and utilities to access smart
    cards.  Its main focus is on cards that support cryptographic
    operations, and facilitate their use in security applications such
    as mail encryption, authentication, and digital signature.  OpenSC
    implements the PKCS#11 API so applications supporting this API
    such as Mozilla Firefox and Thunderbird can use it.  OpenSC
    implements the PKCS#15 standard and aims to be compatible with
    every software that does so, too.
