Make fails in 4.8

[Harold A. Mackey]

Folks
Trying to re-build for ssh vulnerability and encounter this:

[root] /usr/src # make buildkernel KERNCONF=KERBY  
make: no target to make.
"/usr/src/Makefile.inc1", line 158: warning: "make -f /dev/null -m
/usr/src/share/mk  CPUTYPE=dummy -V CPUTYPE" returned non-zero status
"/usr/src/Makefile.inc1", line 773: warning: String comparison operator
should be either == or !=
"/usr/src/Makefile.inc1", line 773: Malformed conditional
((!defined(NO_RESCUE) ||  defined(RELEASEDIR)) &&  (${TARGET_ARCH} !=
${MACHINE_ARCH} || ${BOOTSTRAPPING} < 501101))
"/usr/src/Makefile.inc1", line 773: Missing dependency operator
"/usr/src/Makefile.inc1", line 775: if-less endif
"/usr/src/Makefile.inc1", line 775: Need an operator
make: fatal errors encountered -- cannot continue
*** Error code 1

Stop in /usr/src.

[root] /usr/src # make buildkernel KERNCONF=GENERIC
make: no target to make.
"/usr/src/Makefile.inc1", line 158: warning: "make -f /dev/null -m

GENERIC config file doesn't work either.

Suggestions?
Thanks
