I ran ./configure, but when I try to make llvm, I get the following error:

P.S. I tried installing it by following these instructions - Getting Started: Building and Running Clang

I had the same problem and it was solved by installing a newer version of gcc, which is basically an answer in this thread: How do I use the latest GCC on Ubuntu?

I guess a newer version of Ubuntu (15) automatically solves this problem because the default gcc there is 4.9 already.

I had the same problem, I fixed it by clearing the CMake cache. Just delete CMakeCache.txt and try running make again. CMakeCache.txt should be in the same directory you're trying to execute the CMake command in.
