buildworld for 32-bit powerpc via devel/freebsd-gcc9 at powerpc (not clang): still gets the bss-plt being forced due to crtbeginS.o (build stopped)

As this avoided using system-clang (or any clang), the -secure-plt leading
to bss-plt being forced issue for 32-bit powerpc appears to *NOT* be
clang-specific at all!


I was just curious to see what would be reported. (The system-clang
and devel/binutils at powerpc combination completed buildworld buildkernel.
It reported forcing bss-plt but did not stop early.)

(I have left my old xtoolchain-gcc naming in directory names.)
