Alyssa Ross e6f3d60187 Set LINKER_LANGUAGE for C targets with C++ deps ...

When C and C++ code are being linked together, a C++ compiler has to
be used.  In my experience, this doesn't always cause problems, but it
tends to when doing static builds.

Without this change, I got build failures when I had lerc enabled:
