In #26252 support was added to have prettier paths printed out on failure by not passing the full path to the source file to the compiler, but instead just a small relative path. To preserve this relative path across configurations, the `SREL` variable was used for reconfiguring, but if `SREL` is empty then it will attempt to run the command `configure` which is distinct from running `./configure` (e.g. doesn't run the local script). This commit modifies the `SREL` value to re-run the configure script by setting it to `./` in the case where `SREL` is empty.
