head -r351178 amd64->powerpc (32-bit) cross build using devel/xtoolchain-llvm90: "ld: error: symbol '_ThreadRuneLocale' has no type"

I decided to see what would happen if I tried a
32-bit powerpc buildworld buildkernel (cross
build) based on using devel/llvm90 (after the rc2
update). Where and how it stopped is shown below.
(Note the reference to clang-9 as well.)
