What is the proper way to indicate to Kbuild that something in the
current directory depends on something built in a subdirectory?
Specifically, something like:
obj-y += foo/
obj-y += bar.o
... where bar.o depends on a header file generated inside the foo directory?

Note: in the real-life example there is a lot of bar.o's:
