Wayne Xia - Jan. 25, 2013, 2:43 a.m.
Now libqblock.la can be built with neccessary object files,
and can be automatically cleaned by make clean in root directory.
make libqblock-clean also clean it. -fvisibility=hidden was used
to hide symbols, and a special macro was introduced to export
symbols that marked as public.
