error when creating the vagrant machine: 'features.h' file not found

[gitttt]

When trying to build the vagrant machine:

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.

I confirm the problem, a workaround, rebuild with verbose: VERBOSE=1 TOOL_VERBOSE=1 make -f ../news2e/Makefile Then identify the failing command and relaunch it by hand: make -C /home/vagrant/projects/news2e-build/llvm-3.2.src.native/projects/compiler-rt \ ProjSrcRoot=/home/vagrant/projects/news2e-build/llvm-3.2.src.native/projects/compiler-rt \ ProjObjRoot=/home/vagrant/projects/news2e-build/llvm-native/tools/clang/runtime/compiler-rt \ CC="/home/vagrant/projects/news2e-build/llvm-native/Release/bin/clang" \ LLVM_ANDROID_TOOLCHAIN_DIR="" \ clang_linux

Strangely this succeeds and allows to relaunch the compilation ( i.e. make -f ../news2e/Makefile again). This seem to be a known problem with the path: https://groups.google.com/forum/#!topic/llvm-dev/U4gGLywLwu0

I added a step to the provisioning script to restart the build. While being an ugly workaround, this should fix the problem for now.
