Subject: [PATCH] libxtables: compiler warning fixes for NO_SHARED_LIBS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fixes two issues with NO_SHARED_LIBS:
- #include <dlfcn.h> is ifdef'ed out and thus dlclose()
triggers an undeclared function compiler warning
- dlreg_add() is unused and thus triggers an unused
function warning
Test: builds without warnings

(cherry picked from commit 6cb8af1ff3951e47def7a16db39289dc9d9c61fe)
