We have a mix of substituted lld (`%lld`) and hard-coded lld (`ld64.lld`) commands. When testing with different versions of LLD, this would require going into every place where lld is hard-coded and changing that. If we centralize it, this'll only require us to modify it in only one place and will make it easy to run the same test suite. Plus, this will make it be consistent with how we write other tests.

## This test verifies that we attempt to re-root absolute paths if -syslibroot

## is specified. Therefore we would like to be able to specify an absolute path
|
|
## without worrying that it may match an actual file on the system outside the
|
|
## syslibroot. `chroot` would do the job but isn't cross-platform, so I've used
|
|
## this %t/%:t hack instead.
