* Without the "--with-zlib" configure option, the zlib header will be
  obtained from the build machines "/usr/include" directory if the
  header exists there.
* From ${S}/m4/acx_zlib.m4:

AC_DEFUN([ACX_ZLIB],[
        AC_ARG_WITH(zlib,
                AC_HELP_STRING([--with-zlib=PATH],[Specify prefix of path of zlib]),
                [
                        ZLIB_PATH="$withval"
                ],
                [
                        ZLIB_PATH="/usr"
                ])

        AC_MSG_CHECKING(what are the zlib includes)
        ZLIB_INCLUDES="-I$ZLIB_PATH/include"
...

* Therefore add configure option to point to staging sysroot for zlib
  header and add dependency on zlib.
