You can also do it with eval, without requiring a patch, if you can
somehow find a list of the subdirectories you want to handle.

For example, if you have a list of the target makefiles you want to
build:

    MKFILES = foo/bar.mk bar/baz.mk baz/boz.mk

then you can get a list of directories with $(dir ) etc., then you can
write a loop with eval to declare the proper implicit rules (or even use
explicit ones if you like).
