The problem is that `make install` works with a configuration whose
paths are based on DESTDIR, but as its final act it rewrites
"config.rktd" and other files to strip away DESTDIR. That rewrite tells
the later use of `raco pkg install` to put binaries in the DESTDIRless
path (i.e., "/usr/bin"), and so on. It's a kind of bad luck that `raco
pkg install` runs at all, since it could depend on the DESTDIRless pass
in any number of ways, such as an embedded path in a shared library.

If you really want to go this way, I could extend the makefile to let
you supply a command that runs before the path-fixup step of `make
install`. Then, your "test.mk" would look more like this:

build-arch-stamp: ${base_build_dir}/Makefile
	$(MAKE) -C ${base_build_dir} 
	$(MAKE) -C ${base_build_dir} DESTDIR=${destdir} install \
          FINAL_PREP_CMD="cd $(CURDIR) \
                          && $(MAKE) RACKET="'"'"${PRERACKET}"'"'" \
                                     local-source-catalog \
                          && ${PRERACKET} -N raco -l- \
                                          pkg install ${raco_args} \
                                          main-distribution racket-lib"
	touch $@
