Merge if you like or wait for the real fix to binutils.
This bug has been around for more than a week
since the binutils upgrade was merged and
no one else seems to have noticed so it doesn't
seem urgent.
I needed the work-around to keep our auto-builders happy.
Oh and I did basic sanity testing to show that booting
and systemctl status works on qemuppc.

If you enable systemd and build for qemuppc, then the
compile of systemd fails due to a gold linker failure:
.../powerpc-oe-linux-ld.gold:
error: invalid STB_LOCAL symbol in external symbols
error: linker defined: multiple definition of
'00000001.plt_call.memcpy+8000'
command line: previous definition here
A git bisect confirms that the commit:
0b0f545 binutils-2.28: Update to latest on release branch
is the problem. This is only known to affect powerpc machines.
Work-around this for powerpc by getting configure to use
the bfd linker rather than the gold linker.
This unblocks powerpc use until the linker bug can be resolved.

+Upstream-Status: Inappropriate [other]

+The patch is not appropriate for upstream since it's a temporary
+work-around for only ppc arches. Once the binutils defect in the
+gold linker is resolved, this patch can be dropped.
