commit: https://git.buildroot.net/buildroot/commit/?id=21fdb04eb58b97461c90898aaf2c40c9aa88da7b
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The libnss patch adding ZLIB_INCLUDE_DIR is added to upstream on
2020-01-07 but the 3.49.1 release on 2020-01-13 does not contain this
patch, so we have actually prematurely removed it from Buildroot.

This only affects host-libnss when libzlib is not installed in the host
system. When building for the target, the toolchain-wrapper already
looks in the target sysroot default include path - where zlib.h is
installed.

Re-add this patch, so that we can build host-libnss 3.49.1.

+Add ZLIB_INCLUDE_DIR variable
+
+On Linux platform[1], the build system forces to use zlib from the
+system instead of compiling the one located intree.
+
+The following error is raised when the zlib header is installed
+somewhere else than in the default system include path:
+
+	ssl3con.c:39:18: fatal error: zlib.h: No such file or directory
+	 #include "zlib.h"
+
+The same trick setup for sqlite include directory is reproduced for
+zlib. The build system disallows in any manner to give arguments to the
+compiler explicity.
+
+The variable ZLIB_INCLUDE_DIR point to the directory where the zlib
+header is located.
