Since I haven't been able to reproduce or see the error here, it's hard
to say.

gnutls is in the DEPENDS for libvirt, so everyone should be seeing this if
that was being detected and enabling functionality that wasn't being built.
A quick check of the Makefiles shows that the .c file with the implementation
is being triggered from the same TLS enablement check.

Have you tried modifying the recipe to have an explicit: --with-gnutls (or
--without) ?

Cheers,

Bruce
