So I wasn't expanding the components variables of TESTDIR correctly? I guess I should have at least noticed the TESTDIR was not being assigned using the same operator as BDIR.

I have tried now to use a similar method to copy files into the newly created directories and am having more issues. It seems to me as if the following code,
Code:
# create name for test directory
TESTDIR = ./test/$(OS)_$(KERN).$(ARCH)_$(CNAME)_$(FNAME)_$(ver)
# mkdir if the directory does not exist
${TESTDIR}:
    @mkdir -p ${TESTDIR}

overwrites the original value of TESTDIR which is,

./test/$(OS)_$(KERN).$(ARCH)_$(CNAME)_$(FNAME)_$(ver)

with the mkdir instruction such that if you printed ${TESTDIR} after the
second assignment, it would print,

mkdir -p ./test/$(OS)_$(KERN).$(ARCH)_$(CNAME)_$(FNAME)_$(ver)

with the variables such as $(OS) expanded. This would mean that you could no longer use $(TESTDIR) to refer to the location that was originally assigned.

Is this true or am I not understanding how this is working?
