fatal error: 'wmmintrin.h' file not found

I have started having problem building current more recent versions of 
current.

I am currently running

FreeBSD bsd11 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r320869: Mon Jul 10 
13:57:55 UTC 2017     
root_at_releng3.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64

I have tried nuking /usr/src and doing a fresh svn checkout of the 
current running version
to see if I could rebuild even my current version r320869

/etc/make.conf and /etc/src.conf are empty.

I have

cd /obj
rm -rf

and made sure no remaining files or directories remain.

make buildwould -s


continues to fail as shown below.
