Actually, you don't want to do that.  CFLAGS, CPPFLAGS, and the like
are defined to be "user variables".  That is, the user should be free
to do this:

    make CFLAGS='my flags' ...

If your rewritten CFLAGS contained things necessary for your package,
this would break.

You can set private compiler flags using the `AM_' form of variables:
AM_CFLAGS, AM_CXXFLAGS, AM_CPPFLAGS, etc.
