-Subject: [PATCH] lib: Escape usage of strerror_l() if it doesn't exist in libc
-
-uClibc doesn't implement strerror_l() and thus libnl starting from
-3.2.29 couldn't be compiled with it any longer.
-
-To work-around that problem we'll just do a check on strerror_l()
-availability during configuration and if it's not there just fall back
-to locale-less strerror().

+Subject: [PATCH 2/2] build: add Libs.private field in libnl pkg-config file
+
+In order to support static linking, the libnl pkg-config file should
+indicate in its Libs.private field the libraries that libnl-3.0.a
+requires. The LIBS variable contains the appropriate list of
+libraries: -lm in all cases, and -lpthread when pthread support is
+enabled. This allows to statically link applications against libnl
+properly.

+Subject: [PATCH] Revert "build: enable building cli during tests"
+
+This reverts commit 3cb28534d34392ceec4adead0cfa97039796ccb7.
+
+Contrary to what 3cb28534d commit log claims, the cli programs depend on
+dynamic libraries support of the toolchain. Enabling cli programs
+unconditionally breaks static build as follows:
+
+In file included from lib/cli/cls/basic.c:12:0:
+./include/netlink/cli/utils.h:25:19: fatal error: dlfcn.h: No such file or directory
+compilation terminated.
+Makefile:3666: recipe for target 'lib/cli/cls/lib_cli_cls_basic_la-basic.lo' failed
+make[1]: *** [lib/cli/cls/lib_cli_cls_basic_la-basic.lo] Error 1
+
+Revert that commit to restore the ability of static only build of libnl, and
+its dependencies.
