CXXLINK calls the compiler, so we ought to pass these flags as they
may affect the way the compiler calls the linker in the end.
For instance the compiler might pass on additional objects to
link based on the presence of flags like `-g', `-pg' or

The example you sent to Guido uses `AM_CXXFLAGS = -DSOMETHING'.
I wouldn't expect this to cause any trouble during linking.  Does it?
(If so you should probably change it to `AM_CPPFLAGS = -DSOMETHING'.)

Am I missing something?

I agree this is a bug.  We should honor per-target compiler
flags at link time for consistency.
