My 1st head -r351102 amd64->powerpc64 cross-build via devel/llvm90 failed, but it may be just operator error

My first attempt to cross buildworld buildkernel amd64->powerpc64
via devel/llvm90 without involving devel/powerpc64-binutils (or
other such) failed with:

--- gnu/lib/libssp/libssp_nonshared__PL ---
/usr/local/llvm90/bin/llvm-ranlib: error: Exactly one archive should be specified.

It may well be that the use of some of llvm-as, llvm-ar,
llvm-nm, llvm-objcopy, llvm-objdump, llvm-ranlib,
llvm-size, and llvm-strings is not intended. But I've
not seen a description of the intent.

(My build with devel/powerpc64-binutils involved
completed just fine.)

For reference, devel/llvm90 here is based on ports head
-r509054 providing rc2 of llvm90.
