[hw] Don't export PRJ_DIR in hw/Makefile
This command causes PRJ_DIR to be defined in the environment of
subcommands, but the string PRJ_DIR doesn't appear in any other file
in the repository. Since we don't need it, let's get rid of the hook
before it turns into yet another string of spaghetti :-)
