OK. For me, and given that I followed my make installworld by a
make delete-old. I shouldn't have been surprised that while doing
so, did remove clang. It shouldn't remove what's in /usr/bin. As
the default toolchain for 10+ _is_ clang. So my problem stemmed
from the fact that /usr/bin is searched _prior_ to /usr/local/bin
where my gcc48 is located. Adding the appropriate directives
in make.conf(5) gave me the (g)cc environment I needed to get
past the errors mentioned above. By me, and by others.

Thanks, and sorry for any noise.
