I'm assuming something along the lines of:

your-layer/recipes-support/gnutls/gnutls_3.8.12.bbappend

PACKAGECONFIG:append:class-native = " p11-kit"

until the patch gets picked up in OE-Core. Even if we fix this in 
U-Boot, enabling pkcs11 support in U-Boot (a target recipe) would 
require enabling pkcs11 support in gnutls-native according to the patch 
sent by Franz to the OE ML. This kind of dependency is pretty bad as you 
generally do not want to have to modify a native recipe for a specific 
target machine or configuration. So, I think OE should take that patch.

Cheers,
