lots of undefined references for dynamic eap methods if gnutls isn't used as tls implementation

These are not because of CONFIG_TLS option, but because of
CONFIG_EAP_WSC=dyn not really working. I so not much point for being
able to build this particular EAP method as a dynamic module and I just
removed that option from Makefile to avoid this link problem.

That would be quite surprising and I would expect there was some other
differences in the configuration file, too. I can reproduce (or well,
could reproduce before removing CONFIG_EAP_WSC=dyn from Makefile) this
with OpenSSL.
