Fix builds when make called with CFLAGS_*

When running make CFLAGS_gcc=-DFOO the command line value of CFLAGS_gcc overrides all definitions from the Makefile made with normal = := += operators. However, using the "override" statement, the Makefile can still append to the value given on the command line. We need that for compiling beep-log.c with secure_getenv().
