Bug #39175	mysql_config --libs polluted by $LDFLAGS

Description:
In 5.0.51a, the output of mysql_config --libs started with @SAVE_LDFLAGS@ (usually empty), in 5.0.67, it contains @LDFLAGS@, which can contain flags like -rdynamic which are internal to the mysql build and should not be enforced on programs and libraries using libmysqlclient. This is a side-effect of the fix for bug #31644.

How to repeat:
$ mysql_config --version; mysql_config --libs
5.0.67
-rdynamic -L/usr/lib64/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -L/usr/lib64
^^^^^^^^^
-lssl -lcrypto
