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

[Daniel Mierswa]

When using CONFIG_EAP_*=dyn, CONFIG_DYNAMIC_EAP_METHODS=y and
CONFIG_TLS=gnutls or CONFIG_TLS=internal than the linking fails with:

The same does not occur if i use CONFIG_TLS=openssl
Is this a problem on my machine or is that wpa_supplicant related?

If you still don't like it, that's ok: that's why I'm boss. I simply
know better than you do.
