llvm dev - Aug 2020 - 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

Comment # 3 on bug 46906 from Uday Bondhugula
Thanks very much @jji. I was able to avoid the way you suggested - this
issue
had been a thorn for several weeks. My previous attempts to do a clean
build
were all after a "rm -rf *" and so this hadn't wiped out the
.ninja_log. I
missed that and suspected something in the cmake configuration to the
cause.
