It's the double release jump that doesn't work.  Looking at 7.x the
headers needed are installed in /usr/include.  Similarly 7.x's gcc
has the symbol but doesn't turn on the compiler flags which use it.
Basically RELENG_8 is not completely building against itself.  Trying
to go from 6.x to 8.x is showing some of places where the new OS
doesn't build against itself.

This was with GENERIC for all builds and almost no ports installed.
