don't show the full linker args unless `--verbose` is passed

the linker arguments can be *very* long, especially for crates with many dependencies. some parts of them are not very useful. unless specifically requested:
- omit object files specific to the current invocation
- fold rlib files into a single braced argument (in shell expansion format)

this shortens the output significantly without removing too much information.
