I do not see this problem in 2.4.3-pre2.

The find command is given the real pathname, not the symlink so the
.hdepend and .depend files all contain the real paths. Your problem is
probably this line in the top level Makefile.
TOPDIR := $(shell if [ "$$PWD" != "" ]; then echo $$PWD; else pwd; fi)
TOPDIR must be getting set to the symlink name instead of the real
pathname. Can you confirm what TOPDIR is being set to and why? This
may be a shell problem.
TOPDIR := $(shell if [ "$$PWD" != "" ]; then echo $$PWD; else pwd; fi)
dummy := $(shell echo PWD="$$PWD" pwd=$(shell pwd) TOPDIR=$(TOPDIR) >&2)
