Actually, unless there's more detail to your proposal, that would
totally kill parallelism no?

Since  yacc etc normally handled via .SUFFIX rules
that would imply any rule like

${OBJS}: soemthing

would need to be impacted - that would seriously hurt something like
libc

Adding a special source token, would go a long way to mitigate that.
