This looks good to me, and thanks for fixing the other instances of
BUILD_TOOLS_JDK!

In my experience, using directories for dependencies in make does not work
well. Since all the files in make/data/cacerts are in a flat structure, I would
recommend expressing the prerequisites as:
$(wildcard $(GENDATA_CACERTS_SRC)/*)
This will not cover the case where a file is removed, but that case is rarely
handled well in make based build systems.
But in my experiment, using the directory name does detect the file removal.
It believe that worked well on your machine, but directory timestamp updates
are file system dependent. I'm not sure we can count on all filesystems to
accurately reflect time stamps based on file modification. It's also possible
that an OS would touch directory timestamps for other reasons, which should not
affect the build. I haven't tried having source directories as prerequisites
before, so I simply don't know how reliable it is. My experience is rather with
directories as targets, which certainly doesn't work. If you verified that it
worked as expected on all supported OSes, I would be less worried.
Or, can I list *both* the files and the directory to get maximum awareness?
The directory modification time will usually not change when a file in it is
modified, only when adding or removing files (and possibly some other
operations), so adding the files is certainly a must. If you go with both, then
I would just be worried about potential false positives.
