AliSQL: Fix issue #12: Compile TokuDB SE into embedded library failed

Two problems fixed in this patch:

1. cmake regular expression can't compile for "stdc++";

2. when create libmysqld.a archived library, object files of

   storage/tokudb/ft-index/src/loader.cc and

   storage/tokudb/ft-index/ft/loader/loader.cc conflicts,

   the former is overwrited, and lead to link failure finally.
