[Buildroot] [PATCH] Create zlib installation directory in the staging dir

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Create zlib installation directory in the staging dir

A simple .config with just Busybox and zlib, using an external binary
toolchain, leads to the following build failure:

touch -c /home/thomas/local/buildroot2/build_arm/zlib-1.2.3/libz.so
cp -dpf /home/thomas/local/buildroot2/build_arm/zlib-1.2.3/libz.a /home/thomas/local/buildroot2/build_arm/staging_dir/usr/lib/
cp: cannot create regular file `/home/thomas/local/buildroot2/build_arm/staging_dir/usr/lib/': Is a directory
make: *** [/home/thomas/local/buildroot2/build_arm/staging_dir/usr/lib/libz.so] Error 1

This is because no one creates $(STAGING_DIR)/usr/lib, and the
installation of zlib is done manually. Fix that by creating
$(STAGING_DIR)/usr/lib and $(STAGING_DIR)/usr/include in zlib
installation target.
