LDFLAGS.lld+= vs. 32-bit powerpc related use of ld.bfd in a powerpc64 overall build (head -r356187)

[Mark Millard]

I have historically used the likes of:

# grep -r no-threads /etc/
/etc/make.conf:LDFLAGS.lld+= -Wl,--no-threads

But in trying to build for powerpc64 there is some
32-bit linking as well and it gets the above
involved despite the .lld in the notation. LDFLAGS.lld
being involved at all for a non-lld based link is the
important point, not that I happened to use
--no-threads .

The first error report in the attempted build was:

--- boot1.elf ---
/usr/obj/powerpc64vtsc_clang/powerpc.powerpc64/usr/src/powerpc.powerpc64/tmp/usr/bin/ld.bfd: unrecognized option '--no-threads'
/usr/obj/powerpc64vtsc_clang/powerpc.powerpc64/usr/src/powerpc.powerpc64/tmp/usr/bin/ld.bfd: use the --help option for usage information
cc: error: linker command failed with exit code 1 (use -v to see invocation)
