openssl libraries not found in 32 bits builds

In the fix for bug https://bugs.launchpad.net/percona-server/+bug/1104977, a typo was introduced that prevents the openssl library from being found in 32 bit systems:

   116 if test "$target_cpu" == "x86_64"
   117 then
   118 openssl_libs="-L$location/lib64/ -lssl -lcrypto"
   119 MYSQL_CHECK_SSL_DIR([$openssl_includes], [$openssl_libs])
   120 else
   121 # So it gets set to lib/
   122 openssl_libs="no"
   123 fi
   124
   125 if test "$mysql_ssl_found" == "no"
   126 then
   127 # Now try lib/
   128 openssl_libs="-L$location/lib/ -lssl -lcrypto"
   129 MYSQL_CHECK_SSL_DIR([$openssl_includes], [$openssl_libs])
   130 fi
   131

Line 122 should read mysql_ssl_found=no, so the test at line 125 is affirmative and try lib/. The intent of setting mysql_ssl_found to no was this -- instead, the test is not affirmative and "no" gets added to the CFLAGS incorrectly, having the link fail at build time.

We need to fix the typo and set mysql_ssl_found to no.
