Rather than using linuxapp and bsdapp everywhere, we can change things to use the, more readable, terms "linux" and "freebsd" in our build configs. Rather than renaming the configs we can just duplicate the existing ones with the new names using symlinks, and use the new names exclusively internally. ["make showconfigs" also only shows the new names to keep the list short] The result is that backward compatibility is kept fully but any new builds or development can be done using the newer names, i.e. both "make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc" work.
