Why?

It's the hack that using g++ performs.

Well, g++ does the same extension filtering that gcc does.  It will 
compile .c as C and .C, .cc, .cxx, .cpp as C++.  If either finds source 
in the form of the other then the compilation type is changed.

Another solution would be to use a BUILD_CC variable.  Set BUILD_CC to 
the value of $(CC) for C and the value of $(CXX) for C++ and use 
$(BUILD_CC) in the rules.
