I found something from my old experimental clang
build environment for 32-bit powerpc that I'd
missed undoing when I tried to put things back
to normal.

It turned out to be the reason that R_PPC_PLTREL24
was being generated: -mlongcall was missing in
my build. (There was a time that clang did not
have it but gcc did, so I had it conditional in
my old, experimental environment.)

With -mlongcall back in place as normal (not just
for gcc), system-clang with old ld (cross build)
completes buildworld buildkernel .

The old 32-bit PowerMac is running an official
modern-compiler-based system at last! Cool.
Thanks.

Sorry for the noise.
