This type of error pops up every once in a while, and it usually turns
out that people deleted their /usr/lib/clang directory for some reason,
or if they did a packaged base install, they did not install the
toolchain packages.

In any case, you will have to restore the files in /usr/lib/clang for
the build to continue.


Thank you. Looks like I've compiled stable once without toolchain. 
Installing llvm15 package and use CROSS_TOOLCHAIN=llvm15 during make 
world did it.

Tom
