This, I could not find and used the one from GitHub.

The attached patch [1] resolves the linking error for me, somehow the .got ended 
up first in the DYNAMIC segment. Can you please check if it works for you? 
However, I see a lot of undefined references to cxx.lib.a and pthread stuff 
afterwards. Looks like "-Lllvm/var/abi/arm_v8a"  is missing in the linking 
command of libc++.lib.so. Additionally, "-lgcc" seems a little dangerous.
