Ubuntu 15.10 3.7.1.rc1 - 154 test failures (perhaps my setup is off?)

I tried building and testing the release posted earlier (I checked out the projects: llvm, clang, clang-tools-extra, compiler-rt, and test-suite). I think I’m making a simple mistake, because while the build works – check all fails, so I wanted to ask. Thanks in advance if you can help. Tim

All the projects were checked out with a command similar to

svn co http://llvm.org/svn/llvm-project/llvm/tags/RELEASE_371/rc1 llvm

so I believe I got the tag right.

Sadly, running “make -j4 check-all” I get 154 unexpected failures.

Some info:

tim@arkham:~/Source/llvm-3.7.1/build$ gcc --version
gcc (Ubuntu 5.2.1-22ubuntu2) 5.2.1 20151010

What I did for cmake
cmake -G “Unix Makefiles” -DCMAKE_INSTALL_PREFIX=/home/tim/apps/llvm-3.7.1 …/llvm

Tests that failed listed below:

154 failures looks the same as the output I got from building it too. I don't believe I did anything different to usual.
