I also think it is quite noisy, at least the way it is written. However
I like to have on the target only what's needed.

Hiroshi, do we really need to be so fine-grained when removing things?

Maybe we could do:

GAUCHE_FILES_TO_CLEANUP = \
	$(foreach p,gauche-config gauche-install gauche-package,\
		bin/$(p) lib/gauche-$(GAUCHE_VERSION_MAJOR)/$(GAUCHE_VERSION)/$(GNU_TARGET_NAME)/$(p)) \
	$(foreach p,gencomp genstub precomp,\
		share/gauche-$(GAUCHE_VERSION_MAJOR)/$(GAUCHE_VERSION)/lib/$(p)) \
	share/gauche-$(GAUCHE_VERSION_MAJOR)/$(GAUCHE_VERSION)/aclocal.m4 \
	share/gauche-$(GAUCHE_VERSION_MAJOR)/$(GAUCHE_VERSION)/template.* \
	lib/gauche-$(GAUCHE_VERSION_MAJOR)/$(GAUCHE_VERSION)/include

And then use that variable:

	$(foreach p,$(GAUCHE_FILES_TO_CLEANUP),\
		$(RM) -rf $(TARGET_DIR)/usr/$(p)$(sep))

But it's not significantly better :/
