build system: provide generic compiler flag variables
Introduce generic-$(type)-ccopts and $(class)-generic-ccopts to declare compiler flags that apply to all files of a certain type or of a certain class. Then use them. This is inspired by the commit listed below, but rewritten to match upstream, and split in smaller pieces to keep intent clear.
