*libnice needs c99 for SunOS builds
Update pointer to bulk build message (to be a quarterly one).
Drop libusb1 from pcsc-lite's bl3.

sbin/pcscd is linked with libusb1, but the installed libraries and
headers do not reference libusb at all.  Not including libusb1 avoids
having pcsc-lite's bl3 pull in pthreads to depending packages.
Depend on ../../devel/scmcvs on systems where cvs is not in the "base".
Stop forcing pcsc-lite's library to be the libtool version.

opensc upstream has removed the use of ltdl.  Thus, it is not longer
reasonable to expect it to be able to dlopen a .la file.  So pass the
.so, not the .la, to configure, when using the pcsc-lite (default)
option.  Resolves a failure of pkcs15-init to load modules.
