Sort configure options

Stick to the order of 'configure --help' for most sections, but
sort environment variables alphabetically (since, e.g.,
configure --help does not list CPPFLAGS and there is not a good
way to add that).
Note that this does not add or remove any content, even though
some options are missing/extra.
