Linux makefiles shouldn't hard code g++/gcc

I don't know if this has been covered, but there is a bug in the Linux makefiles. I believe the makefiles hard code the use of g++/gcc when I think they should use $(CXX) and $(CC). This way Fedora Core 4 users can install the gcc-compat (or compat-gcc, never remember) packages and compile Torque by overriding the compiler:

export CXX=g++32
export CC=gcc32

before starting make.
