-r is used for relinking. The idea behind the change was to make it directly 
suitable for that. It takes object files and relinks them into a new object 
file. It gives the caller complete control.

It sounds like you are missing some way to add startfiles? A reverse of 
-nostartfiles?

But hopefully you can just use the linker directly? Unless you have LTO 
enabled object files you dont need the compiler to link.
