You can enable both, for example by "%s".

Let me speak generically: Let's take "FOO" as our constant, and
"EXTRA_FOO" as the environment variable. By default, the contents
of EXTRA_FOO will _replace_ the contents of FOO (unless EXTRA_FOO
is not defined), but EXTRA_FOO may include "%s", which will be
translated to the contents of the original FOO. For example, if
CFLAGS is set to "-c", and EXTRA_CFLAGS is set to "%s -DDEBUG",
then the result will be "-c -DDEBUG".

Alternatively, we can use different names; EXTRA_FOO will be used
to ADD contents, MY_FOO will REPLACE the original FOO, etc.
