We need to account for path rerooting when generating the response file. We could either reroot the paths before generating the file, or pass through the original filenames and change just the syslibroot. I've opted for the latter, in order that the reproduction run more closely mirrors the original. We must also be careful *not* to make an absolute path relative if it is shadowed by a rerooted path. See repro6.tar in reroot-path.s for details. I've moved the call to `createResponseFile()` after the initialization of `config->systemLibraryRoots`, since it now needs to know what those roots are.

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

|
|
## 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
