[GRASS-dev] Compilation flag for OpenMP

Hello,

While compiling a module with OpenMP (-fopenmp) I can include it in the module
make file, and the *.o files are created with parallelization in
i.module/OBJ*/ dir.

Now when compiling GRASS, I'd like it to know there is a need to look at this
module with OpenMP in mind. Is there a nice way to do that?

thank you,
Yann
