Summary

I have got build failing on NetBSD for several days with the following error:

Are you sure your sources are up-to-date? That file is newly generated in LLVM and no changes outside should be necessary. Are you using cmake or gmake?

Yes. This is also the reason to kill randomly buildbot building.

CMake + ninja: http://lab.llvm.org:8011/builders/lldb-amd64-ninja-netbsd7

It is obviously missing dependency.
How to reproduce;

$ ninja -t clean
$ ninja clangFrontend

FYI, this is reported also in; https://llvm.org/bugs/show_bug.cgi?id=25565

Sorry for the delay. I had an issue in my network.
