  I (and I think Peter as well) prefer the more verbose

ifeq ($(BR2_PACKAGE_DTC_BINARY),y)
DTC_INSTALL_RULE = install
else
DTC_BUILD_RULE   = libfdt
DTC_INSTALL_RULE = libfdt_install
endif

  I would also call it _TARGET instead of _RULE.

  I would prefer the same rule for staging and target install:

- it doesn't hurt to have the executable in staging;

- it's easier to read if it's the same;

- when we finally get around to creating $(make-package), the default install
commands will be
$(MAKE) -C $(@D) DESTDIR=... $($(PKG)_INSTALL_TARGET)
(where _INSTALL_TARGET is the same for target and staging and defaults to
'install')
