comment Forcing GNU make to run commands in order
The semi-"standard" way to redirect both standard out and standard error is >&, not &>. Bash and zsh support both. The various csh descendants only support the first. The nice thing about the first form is that on shells that don't support it, it is more likely to error, rather than run the command in the background.

comment Four tasks in parallel… how do I do that?
There are also "gnu parallel" and "xjobs" designed for this case. It's mostly a matter of taste which you prefer.

comment Creating recursively sorted RAR archive
find . is more idiomatic than find *. If you need to get rid of the "./" component, find -printf "%P\n" works. If your tools can handle NULs, I would actually recommend find . -type f -printf "%P\0" | sort -z | xargs -0 rar a ../foo.rar, as it properly handles filenames with newlines. Actually, I'd recommend find dir -type f -print0 | sort -z | xargs -0 rar a dir.rar, as it's considered polite in unix-circles to unpack archives into subdirectories. The -type f is needed: the containing directory gets sorted before its files, and rar will pack them using the directory order.

"dak" is listed as a rare variant in the jargon file. I've never actually heard it though.

Why can't you just use a vfat filesystem, which allows long file names?
