Chris Kay f4dd18c270 build: consolidate directory creation rules 
This commit streamlines directory creation by introducing a single
pattern rule to automatically make directories for which there is a
dependency.

We currently use several macros to generate rules to create directories
upon dependence, which is a significant amount of code and a lot of
redundancy. The rule introduced by this change represents a catch-all:
any rule dependency on a path ending in a forward slash is automatically
created.

Now, rules can rely on an unordered dependency (`|`) on `$$(@D)/` which,
when secondary expansion is enabled, expands to the directory of the
target being built, e.g.:

    build/main.o: main.c | $$(@D)/ # automatically creates `build/`
