This is a rule taking two parameters.

Here's, what are the values you pass for 'module-name'
and 'variables' parameters? I'm pretty sure that 'module-name'
is not 'rules', so I'm not at all surprised this returns nothing.

   [ rule.peek rules : CFLAGS ] 

might be better, or even better, define 'cflags' *rule* in
your rules module
