Some libraries are not copied during SDK installation

I do:

make
make sdk_install_pkg
and subsequently install the .bin file, libraries like tsetjmp are not copied in the destination directory. I can't compile my code with -lsgx_tsetjmp. tsetjmp is not the only one....

I just made a quick script to copy all the .a files in the repo's sdk directory in my destination directory under lib64 and it worked out.

Reproduce the issue with `make`, `make sdk_install_pkg`, and the generated `.bin` installer, then inspect which libraries from the SDK directory are included in the destination `lib64`. Compare the installed contents with the SDK's `.a` files; done means libraries such as `tsetjmp` are included and code using `-lsgx_tsetjmp` can compile.
