If I read this correctly, it patches clang without patching
lld to accept --secure-plt when its output is for the
likes of elf32ppc_fbsd . (At least for cross builds that
target elf32ppc_fbsd .)

So it appears to be this does not enable llvm80 use
overall, at last for how buildworld is set up: it uses
--secure-plt with ld.

(It turns out that clang8 output and devel/powerpc64-binutils
for -m32 can mismatch and system-clang with
devel/powerpc64-binutils can not buildworld: ld reverts
to bss-plt sometimes and returns an error code when it does
so. I expect that the devel/llvm80 result would be the same
now.)
