Hosting core.mk files outside the base-hw repository is a new pattern
for us, but I see the appeal.
REP_DIR always points to the repository where the target resides - in
your case, this is the core.mk library. The simplest solution would be
to replace the occurrences of REP_DIR in core.inc by a new variable
BASE_HW_DIR, which has to be defined by the one to includes core.inc.
The core.mk files within the base-hw repository would simply define to
as $(REP_DIR) but your "foreign" core.mk file could set the variable
explicitly to the location of the base-hw repository.
Would that solve your problem?
