Make all 1985 entries compile under linux

Unfortunately some entries will either not compile under macOS or not
run correctly. We used a patch from Yusuke Endoh for
1985/applin/applin.c. Thank you Yusuke! This is actually the entry that
does not work right under macOS but it does under linux.

Update main README.md with links.

Update a number of other README.md files with typos and other fixes and
improvements (including fixing invocations and adding a 'Try:' section
to match later year README files).

Update various Makefiles to add notes and to make some entries compile
(in some cases, those that require -traditional-cpp, they will not
compile under clang and we note this).

Update archive/archive-1985.tar.bz2. Why? Because the purpose of the
archive/ files are for the original files and some of the files in there
were not original. See the files 1985/lycklama/lycklama.orig.c and
1985/shapiro/shapiro.orig.c which in the tarball do not have the .orig
added to the name.
