Well, again with Clang-3.6, the nightlies run fine*, I run them like this:

CXXFLAGS="-stdlib=libc++" LDFLAGS="-lc++ -lc++abi" sandbox/bin/lnt 
runtest --submit perfdb nt --sandbox sandbox --cc 
trunk/build/release/Phase3/install/bin/clang --test-suite llvm-test-suite

This builds the tests with libc++ and libc++abi.

Since the LDFLAGS are prepended instead of appended, I have to specify 
-lc++ before -lc++abi.

I'm yet to backport or fudge the cmake build for Clang-3.5.

I'm currently thinking of adding
-enable-libcpp    Use libc++ if available. [default: disable]
-use-cmake        Use cmake build system instead of make.

To test-release.sh
