--with-zlib seems to have no effect on libsvn_delta

[亚男（Timandes）]

This is my configuration options:

 # ./configure --prefix=/usr/local/subversion-1.8.11 \
  --with-apr=/usr/local/apr-1.4.6/bin/apr-1-config \
  --with-apr-util=/usr/local/apr-util-1.5.1/bin/apu-1-config 、
  --with-sqlite=/usr/local/sqlite-autoconf-3071501 、
  --with-zlib=/usr/local/zlib-1.2.8

after that, is:
# make && make install

But when i try to use it, i found this warning:
# /usr/local/subversion-1.8.11/bin/svn --version
/usr/local/subversion-1.8.11/bin/svn: /lib64/libz.so.1: no version
information available (required by
/usr/local/subversion-1.8.11/lib/libsvn_delta-1.so.0)
svn, version 1.8.11 (r1643975)
...

Then i realize that configure program maybe use pre-installed zlib in my
system.
# ldd /usr/local/subversion/lib/libsvn_delta-1.so.0|grep libz
/usr/local/subversion/lib/libsvn_delta-1.so.0: /lib64/libz.so.1: no version
information available (required by
/usr/local/subversion/lib/libsvn_delta-1.so.0)
        libz.so.1 => /lib64/libz.so.1 (0x00007ff5c959c000)
