adding --hint:cc doesn't trigger a recompilation with nimBetterRun

[timotheecour]

EDIT:
explanation:
what's going on is that adding --hint:cc does indeed trigger nim compilation (because cmd line changed), as you can see with --hint:Processing

but it doesn't (typically unless you're doing smthg that depends at RT on this) trigger a "CC" rebuild, probably bc c files are same?
