Nailed it.  After the post by Michael, I edited the kernel several
times.  I'm sure I ruled that thing out.  I had some crc stuff not there
but same error with or without.  I admit, I wouldn't have thought of a
kernel driver issue but the error did sort of lead that way.  Given the
CPU FLAGS is about the CPU and its instruction set, it could be a option. 

I would never have thought of the CFLAGS in make.conf.  I'm not sure how
you figured that out either.  o_O  Before trying new settings for that,
I tried newer versions of clang, llvm and their friends to see if there
was a fix that wasn't applied to older versions.  When you unmask one
thing, it snowballs a bit.  Anyway, after getting a more recent version
of clang and llvm, it still failed.  At that point, I suspected that I
had ruled out those packages.  I did some digging to find what my CFLAG
settings should be if done manually.  It took some digging tho.  Once I
set that to the manual way, it compiled successfully on the first try. 

So, my backup rig now has a web browser.  That's good.  ;-)  I wonder
why that bug report wasn't in the search results when I was digging for
the error???  If I see something Gentoo related, I always look. 

While at it.  I don't think there is a way but I may have missed it.  As
a example, when I wanted to unmask/keyword specific versions of llvm and
clang, is there a tool to find out what all else has to also be
unmasked/keyworded?  When I tried to do that for the packages I wanted,
I ended up running emerge to find more that had to be added to the
list.  This is the list I ended up with. 


sys-devel/clang
sys-devel/llvm
sys-devel/clang-common
sys-devel/clang-runtime
sys-devel/clang-toolchain-symlinks
sys-libs/compiler-rt
sys-libs/compiler-rt-sanitizers
sys-libs/libomp
sys-devel/llvm-toolchain-symlinks
sys-devel/llvmgold



It would be nice if there is a way to just run a command once and it
spits out a friendly list that can be added to the proper file.  Save
annoying some electrons and all.  ;-) 

Thanks much to you both.  I hope if someone else runs into this, this
thread pops up in the search results.  Save someone some head scratching.

P. S.  Switched computer case door to left side hinge the other day. 
Put in the drive trays and figuring out if there is a way to put drives
in other places and still have lots of fans.  :-D
