After building world and kernel r340097, kernel runs fine, but every
userspace program in world crashes with Illegal instruction. They all
crash in exactly the same way. Example backtrace from bmake, running
from objdir (first discovered after updating a poudriere jail and
attempting to even start it):

Reading symbols from
/usr/obj/usr/src/amd64.amd64/usr.bin/bmake/make...Reading symbols from
/usr/obj/usr/src/amd64.amd64/usr.bin/bmake/make.debug...done.
done.
[New LWP 100097]
Core was generated by `/usr/obj/usr/src/amd64.amd64/usr.bin/bmake/make
--help'.
Program terminated with signal SIGILL, Illegal instruction.
#0  0x00000000002f5664 in _init ()
(gdb) bt
#0  0x00000000002f5664 in _init ()
#1  0x00000000002290fe in _start (ap=<optimized out>, cleanup=<optimized
out>) at /usr/src/lib/csu/amd64/crt1.c:66

Given the line number referenced in crt1.c, I'm guessing this condition
may have existed since at least r339351.

Can't think of a witty .sigline today…
