For 6809 build, allow Linux, VT52 and ANSI versions to co-exist, and build them
all.
May want to do the same for z80 if ANSI terminals are available there? The
Linux version is just for host testing purposes.
Expand package file to include both versions, if they exist, to add the man
page and to add appropriate links for ease-of-use.
