I have a few suggestions:
* The tests above this block test for default (i.e. generated by the driver
automatically) linker flags when generating an executable. This block does
something very different. I would separate the two things into different files.
* Why would we test `-shared` and `-static` in one invocation?
* We should make sure that what's being tested is indeed the linker invocation.
This can be done by e.g. adding something akin `! UNIX-LABEL:
"{{.*}}ld{{(\.exe)?}}"` to make sure that it's indeed the linker invocation
that's being matched.
