hangs with active p11-kit modules

[Sven Geggus]

Hello,

I encounter strange hangs on various pieces of software (cups, mutt, ...)
linked against gnutls (2.12.x) with an active pkcs11 smartcard module. This
module is not used by these applications, they are just linked against
gnutls.

This goes this far that building gnutls with an active pkcs11 module takes
ages because of very long delays in various gnutls self-tests and after some
very long delay in almost every single test the build fails with the following 
messages:
