What circumstances ? CPPFLAGS+= overrides (discards) values in the
environment as well as ones from the command line.
Providing a definition in config-host.mak involves duplicating the
value, which can't be right. If there's no other way to do it then
there should be a reference to USER_CPPFLAGS or some such but frankly
that's a pain and overkill.
