The following is more informational than anything as far
as I'm concerned. But there may be implications that I'm
unaware of. (I sometimes experiment with toolchain use
to see what the current status is for such use.)
In attempting to buildworld buildkernel via
powerpc-unknown-freebsd13.0-gcc9 (via amd64->powerpc
cross build):
