When I compared this to other builds, I noticed a missing bit:
===> usr.bin/clang/clang (all)
===> usr.bin/clang/clang (install)

usr.bin/clang/Makefile has this near the top:
.if ${MK_CLANG} != "no"
SUBDIR+=        clang
.endif

If I read this right, it means that the actual clang is not built/installed if 
WITHOUT_CLANG is configured.
Even in the cross-tools stage!

I am not sure how it worked before as I do not see any recent changes in that 
direct area.  Not sure when and what went wrong.  Maybe it's something in one of 
.mk include files, maybe something in my environment.

As hack I tried this change and it seems to have helped:

I hope that more knowledgeable people can see what the problem could be, 
wherever it is.
