Make outdir board-specific to avoid build collisions
Casual building in the tree leads to regular messups where I forget to
clean up the outdir first when switching platforms and the build fails
in strange ways.
Put a $(BOARD) subdirectory under outdir, and use that at $(O) when
the user does not provide an output directory.
Note that "make pristine" continues to remove the entire outdir,
including other architecutres (so as to make the tree pristine).
Also update a few spots where outdir was mentioned in documentation to
clarify the new scheme.
