I'm assuming your makefile actually says "include $(BUILD_DIR)/Makefile.inc"

This won't work: make does not expand backquotes.  Backquotes are a
shell feature, not a make feature.

If you're using GNU make you can use the $(shell ...) function:

  BUILD_DIR := $(shell current_tag)

This is not portable to other versions of make of course.
