Description:
I find that libmysqlclient_r.so is linked with the library options "-lpthread -lcrypt -lnsl -lm -lpthread", while libmysqlclient.so is linked with "-lcrypt -lnsl -lm -lz".  The lack of -lz for libmysqlclient_r.so causes "compress" and "uncompress" to show as undefined symbols when a client tries to use that library.

How to repeat:
1. Build with "--enable-shared --enable-thread-safe-client".

2. ldd -r libmysqlclient_r.so.14.0.0

3. Note undefined symbols and lack of dependency on libz.  Compare to output for libmysqlclient.so.

Suggested fix:
I think this is because configure only inserts ZLIB_LIBS into NON_THREADED_CLIENT_LIBS; is there a reason that zlib isn't just added to LIBS?

Added ZLIB_LIBS to libmysql_r/Makefile.am
