ninja: error: remove(include/llvm/Support): Directory not empty

FYI. In case someone is also experiencing this glitch…

I think this should be a bug of ninja,
it failed to clean deprecated entry in .ninja_log for include/llvm/Support .

You should be able to avoid the problem by either
1. delete the deprecated line in .ninja_log
sed -i -e "/include\/llvm\/Support[^/]/d" .ninja_log
2. delete .ninja_log.
3. do a clean build with ToT in a new build dir
