Sorry, I forget what Greg's proposed mechanism is.
Perhaps you could a patch to place @YOUR_MAGIC_VARIABLE@ into the
relevant config file, and a post-patch target using sed to replace
@YOUR_MAGIC_VARIABLE@ with the desired value. This way, the patch
command can worry about context, and the sed command can blindly make
the substitution without worrying about context. You could probably
use the existing FILES_SUBST framework. (Oops, FILES_SUBST is not
documented in Packages.txt.)
