[I experiment with clang based worlds and kernels
on powerpc64 and powerpc.]
This was a poudriere-style build. pkg builds too early
to allow devel/binutils or devel/powerpc64-binutils
to be build first in order to use that linker or other
such utilities. Thus, /usr/bin/ld is in use. (lld is
not yet an option, last I knew anyway.)
This make poudriere ineffective for the powerpc64
context with clang as the system compiler.=20
