This way I still link a shared library. libboost_python.so is a symbolic
link to libboost_pyton.so.1.33.1.
I link my software with libboost_python.a, it will be statically link. It
works on x86 32 bit Linux. But on x86_64 system, since we compile our
software as a .so package and want to statically link libboost_python.a,
linker complain we need compile libboost_python.a with '-fPIC' flags. Same
complain for all other dependency packages we need.
