I suspect that Python wants PYTHONPATH to use Windows syntax, e.g. 
(untested):

-	PYTHONPATH="$(GISBASE)/etc/python:$$PYTHONPATH" \
+	PYTHONPATH="$(call mkpath,$(GISBASE)/etc/python,$$PYTHONPATH)" \
+
+ifneq ($(MINGW32),)
+mkpath = $(shell g.dirseps -h $(1))\;$(2)
+else
+mkpath = $(1):$(2)
+endif

MinGW transparently converts filename and path syntax for environment
variables which it knows about (e.g. PATH), but probably not for
PYTHONPATH.
