Split independent commands in make recipes

Mostly, there is no need for joining commands with `&&` in recipes
since make already applies the exit-on-error functionality to each
executed line, unless there is a shell interdependency between them
(like setting environment variables in one command and using it in
another, or changing the working directory, which would not work
because of the new-subshell-per-line behaviour of make). Thus, some
independent commands can be split in the `Makefile` to improve
readability.

(Some space/tab inconsistensies are also fixed.)
