I have a similar (identical?) failure from sources updated yesterday,
however I have MKLLVM=no (and MKLLVMRT=no).
But as Thomas did, I also have MKDEBUG=yes and MKDEBUGLIB=yes.
The build host is running amd64 9.99.64 (dated from about 2020/06/09).
What's totally odd though is that there's no change whatsoever in
external/bsd/libc++/ between the source tree the build host was
successfully self-built with, and the sources from yesterday.
So, I'm guessing this must be due to the change in the toolchain between
last June and now. Interestingly right after the message I'm replying
to was another from Thomas titled "new gcc8/gcc10 build breakage between
9.99.63 and 9.99.67".
Luckily I've saved both the old source tree and the old build directories.
