[George Rimar via llvm-commits]

Loos like it is -z relro (but I didn`t check what will be if ignore it, probably there are other ones also):
Full log is below:

CMake Error at /usr/share/cmake-3.0/Modules/CMakeTestCCompiler.cmake:61 (message):
  The C compiler "/home/umb/LLVM/build/bin/clang" is not able to compile a
  simple test program.
  It fails with the following output:
