I can't think offhand of any bad thing that would result from doing
that.  It certainly might be worth a try. 

On the other hand, I also can't think offhand of any significant way in
which the gcc builds for different subarches are going to be different.
The architecture selection is all done at run time using -march in
CFLAGS, isn't it?
