I've solved my own issue. Sorry for the chatter.

The second location was because the 'source' directory was copied over to
the 'build' directory, which was built previously for my host RCC. So it
had the same artifacts from beforehand due to the previous build.

The issue was that my cross compiler did not have a tool called `c++`, but
only `g++`. I could either make a symbolic link in my path from
{cross}-c++ -> {cross}->g++, or add a patch to be applied to make it say
g++ instead of c++ for the CXX tool in the SConstruct file.

Essentially, without a working C++ compiler, libgpsmm.o would not get built
and things would fail.

Again, sorry for the chatter.
