Order of options is indeed a bit of a problem, as the code that puts them together more or less assumes that the order does not matter, which is not true for programs like ld.
Off the top of my head, I don't know how to achieve the above. It's particularly complicated due to the "grouping" requirement (--start-group/--end-group is the same thing conceptually). Perhaps such things will need dedicated properties (where?) with special handling? Ideas welcome. Perhaps we should gather them in a JIRA task.
