just following up on this thread - i assume others have been able to 
buildworld on amd64, and have not been getting this linker error?  i 
have a fresh checkout from this morning, tested with and without ccache 
and am still getting this same error.  my system is currently at this 

$ uname -ar
FreeBSD runner 12.0-CURRENT FreeBSD 12.0-CURRENT #1 63d5d6c71fb(master): 
Sat Nov 18 08:36:45 PST 2017 
pwright at runner:/usr/obj/usr/home/pwright/git/freebsd/amd64.amd64/sys/GENERIC-EVDEV 

any tips on helping debug this as well would be appreciated - as i'm not 
%100 sure where to start (i.e. how to invoke the linker with the "-v" 
flag for buildworld :)
