Apparently not from what I've seen in the lists. It will be a couple/few weeks 
before I again have powerpc64 or powerpc access. I've just been monitoring 
powerpc64 & powerpc things in hopes of things working once I have access again 
--or at least my knowing what to do to sidestep issues and what sequence to 
progress in from what I had in very early 2016-June when I lost access 

May be someone will have the time & knowledge to bisect the upstream binutils 
materials. I may figure how to sometime after I get access again. But it is not 
the only FreeBSD powerpc64 (PowerMac) thing that I'd likely be investigating. 
(Example: because of problems with sprg0-value handling for FreeBSD vs. 
OpenFirmware on PowerMac powerpc64's: testing usefdt=1 mode for Nathan 
Whitehorn in hopes of future changes avoiding OpenFirmware use from FreeBSD. 
Nathan put the hooks in place for testing somewhat after I'd already lost 

I wonder if the various(?) binutil port(s) that are 2.27 based now and can be 
built to target powerpc64/powerpc should be marked broken for powerpc64/powerpc 
until this is figured out. Any ports that are only for targeting powerpc64 or 
powerpc probably should not be at 2.27 at this point.

I've submited a bugzilla report 212868 for devel/binutils with the text of the 
list reports that I've quoted.
