Ah. It seems to work here (GNU Make 3.80):

$ rm -f myprog subdir-libs.dummy subdir/mylib subdir/ronron
$ make myprog
make -C subdir libs
make[1]: Entering directory `/space/tmp/make-recur/subdir'
touch ronron
touch mylib
make[1]: Leaving directory `/space/tmp/make-recur/subdir'
touch myprog
$ make myprog
make -C subdir libs
make[1]: Entering directory `/space/tmp/make-recur/subdir'
make[1]: Nothing to be done for `libs'.
make[1]: Leaving directory `/space/tmp/make-recur/subdir'
$ touch subdir/ronron
$ make myprog
make -C subdir libs
make[1]: Entering directory `/space/tmp/make-recur/subdir'
