 Well, I never proposed to introduce an extra stamp file, did I? :-)

 The reasons you put forward are OK, they should just be mentioned in the commit
message because it's a change from how things are currently done, and this
should be motivated. That way, if someone later on finds a reason to revert to
repeating the fixup, they can see why it was done this way to begin with.

 BTW, it doesn't really avoid duplication of code. Now we have repetitions of

$(UCLIBC_DIR)/.stamp_configured: $(UCLIBC_DIR)/.stamp_config_fixup_done

and otherwise we'd have repetitions of

define UCLIBC_CONFIGURE_CMDS
	$(UCLIBC_FIXUP_DOT_CONFIG)
