Essentially, I think that CCLD should be a CXXLD. animate is written C,
but some of the libraries are written in C++. The compilation works if
I manually /usr/pkg/gcc49/bin/c++ the -o utilities/.libs/animate linking
step.

One question is how automake is meant to know to link using C++,
the other is why doesn't it break from me compiling ImageMagick on
NetBSD-current?
