Failed Android build: "error: relocation overflow in R_ARM_THM_CALL"

Ok, everyone.

We finally solved the problem, a external dependency libcurl haven’t been correctly compiled. So we have recompiled it and you can refer to this PR to have all necessary changes in external curl folder:

https://github.com/cocos2d/cocos2d-x-3rd-party-libs-bin/pull/54/files

Actually we added -fPIC flag to compile lib curl to solve the problem.

Yet we still don’t know why this is happening on some devices and not on others.
