Dominique Martinet ccb36a5849 cmake: change how warning flags are added ...

Setting CMAKE_C_FLAGS_DEBUG does not work as first expected:
 - set(... CACHE) didn't do anything because the variables were
initialized previously
 - We could set with FORCE but then users could not change the value
 - There is a way to only do that on initial cmake run but it has the
same problem

Thus, use a new regular cache variable directly instead
