I'm on a mac and have a vanilla mozilla-central checkout as of:

My mozconfig is

> ac_add_options --enable-stylo
> export LLVM_CONFIG=/Users/tritter/.mozbuild/clang/bin/llvm-config

The build fails with

> 0:15.37 /Users/tritter/.mozbuild/clang/include/c++/v1/wchar.h:119:15: fatal error: 'wchar.h' file not found, err: true
> 0:15.37 /Users/tritter/.mozbuild/clang/include/c++/v1/stdlib.h:94:15: fatal error: 'stdlib.h' file not found, err: true
 
The complete build output is attached (this is the second ./mach build, so there's some things skipped that presumably built fine the first time.)

If you run `xcode-select --install`, does this fix the issue?  If so, this is a dupe of bug 1366564.
