head -r326192: Under clang pkg-static (1.10.2) fails to link on powerpc64: "libtool: warning: complete static linking is impossible in this configuration" (later crashes)

[Mark Millard]

[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.

/usr/libexec/gdb shows:
(/usr/local/bin/gdb core dumps)

Core was generated by `/usr/bin/ld --eh-frame-hdr -dynamic-linker /libexec/ld-elf.so.1 --enable-new-dta'.
