Revert "Mac: set -obj_path_lto when building with LTO"

This reverts commit fb34ab468f55c8c383b31b341544627cb97efb25.

Reason for revert:

Original change's description:
> Mac: set -obj_path_lto when building with LTO
> This temporarily saves intermediate object files (other than cache hits
> which are already persisted in the cache directory) so that `dsymutil`
> can read the debug info out of them.
> This change also adds an argument to to clean this
> directory up after `dsymutil` has run. I'm not sure this is the best
> way to do it, so very open to other suggestions.
