[PATCH 3/3] gnutls: link against 'dl' library

[Otavio Salvador <otavio@ossystems.com.br>]

Fixes a build failure due missing references to 'dlopen' and
like. This started to happen after update to 2.12.5 at
ad52eacebdc413aa351de078ee878182a9c71e16. This also fixes the recipe
to use the INC_PR value otherwise we end not bumping PR if changing
only the '.inc' file.
