AND LIBCRYPTO

Problem: libmysqlclient_r exports symbols from yaSSL library which
         conflict with openSSL symbols. This issue is related to symbols
         used by CURL library and are defined in taocrypt. Taocrypt has
         dummy implementation of these functions. Due to this when a
         program which uses libcurl library functions is compiled using
         libmysqlclient_r and libcurl, it hits segmentation fault in
         execution phase.

Solution: MySQL should not be exporting such symbols. However, these
          functions are not used by MySQL code at all. So avoid compiling
          them in the first place.
