CC and LDFLAGs are hardcoded and breaks cross compiling

[Kyle Manna]

Don't define CC, as make will default to cc which is typically a symlink to gcc anyways. This allows build tools (such as openembbed + bitbake) to override these for cross compiler variables.

Furthermore, CXX for the C++ compiler is actually desired, so change that as well. Make will use "c++" which is typically a symlink to g++ as well.

Also make LDFLAG assignments append the value rather then override the environment values passed in.

Users can override these from the environement if so desired.

This bug also affects me.

Is there a reason the suggested patch isn't applied?
