m vs p doesn't make much difference.

Don't forget about package/Makefile.autowhatever.in.
This needs adjustment too.
(and whoever hard-coded x11 specific stuff in there should be beaten)

Yes. Not sure if that'd work, but perhaps something like
$(PROJECT_BUILD_DIR)/%/$(FOO_BINARY): $(TARGET_DIR)/$(FOO_BINARY) \
	$(TARGET_PACKAGES_DIR)/$(FOO_BINARY): $(FOO_DIR)/.unpacked
	$(MAKE) -C $(FOO_DIR) et cetera

may do the trick. We'd have to see if something like that makes sense.

$ svngrep -r ^TARGET_DIR:= /mnt/cvs/busybox/upstream/buildroot/ 2> /dev/null
/mnt/cvs/busybox/upstream/buildroot/project/Makefile.in:TARGET_DIR:=$(PROJECT_BUILD_DIR)/root

yeah. I'll reread the dropbear example tomorrow. Perhaps somebody else
has other comments.
